HIGHWAY AUTO AND LIGHT 
TRUCK TIRE REPLACEMENT AND 
ADJUSTMENT POLICY (EXCLUDES 
GOODYEAR UNISTEEL
® RADIAL 
LIGHT TRUCK TIRES)
WHO IS ELIGIBLE?
You are eligible for the benefits of this Limited 
Warranty if you meet all the following criteria:
• You are the owner or authorized agent of the 
owner of new Goodyear or Dunlop highway 
auto or light truck tires supplied as Original 
Equipment on your vehicle.
• Your tires bear Department of Transportation  prescribed tire identification numbers.
• Your tires have been used only on the vehicle  on which they were originally installed 
according to the vehicle manufacturer or 
Goodyear’s recommendations.
• Your tires were purchased on or after  September 1, 2012.
Light truck tires are defined as all tires 
identified with the “LT” designation in the 
sidewall stamping.
WHAT IS COVERED AND FOR 
HOW LONG?
FREE TIRE REPLACEMENT
Any new Goodyear or Dunlop highway radial 
auto or radial light truck tire, covered by this 
policy, removed from service due to a covered 
warranty condition during the first 2/32” of 
usable treadwear or twelve months from date  of purchase, whichever comes first, will be 
replaced with a comparable new Goodyear or 
Dunlop tire at no charge, including mounting 
and balancing. (Without proof of purchase the 
date of manufacture will be used to determine 
eligibility.)
ALL OTHER HIGHWAY AUTO OR LIGHT 
TRUCK TIRES
Any new Goodyear or Dunlop highway auto 
or light truck tire, other than radial auto, radial 
light truck tires, removed from service due to 
a covered warranty condition during the first 
1/32” of usable treadwear will be replaced 
with a comparable new Goodyear or Dunlop 
tire at no charge, including mounting and 
balancing.
TEMPORARY SPARE TIRES
Any Goodyear or Dunlop temporary spare 
tire removed from service due to a covered 
warranty condition during the first 50% of 
usable treadwear (1/32”) will be replaced 
with a comparable new Goodyear or Dunlop 
temporary spare tire at no charge, including 
mounting.
PRORATED ADJUSTMENT
Tires not eligible for free replacement that 
are removed from service due to a covered 
warranty condition will be replaced with a 
comparable new Goodyear or Dunlop tire on a 
prorated basis for up to six (6) years from the 
date of original new tire purchase or when the 
treadwear indicators become visible (worn to 
2/32”), whichever occurs first. (Without proof 
of purchase the date of manufacture will be 
used to determine eligibility.)
HOW WILL PRORATED CHARGES 
BE CALCULATED?
Replacement price will be calculated by 
multiplying the tire’s advertised retail selling 
price at the time of adjustment by the 
percentage of usable original tread that has 
been worn off. You pay for mounting and 
balancing, and an amount equal to the current 
Federal Excise Tax (F.E.T. – U.S. only) any other 
applicable taxes and government-mandated 
charges.
EXAMPLE: If your disabled tire had an original 
8/32” of usable treadwear and is worn to 
4/32” usable tread remaining, you have used 
50%, and therefore must pay 50% of the 
advertised retail selling price of the comparable 
tire. 
In addition, you must pay an amount equal to 
the full current Federal Excise Tax (U.S. only) 
or any other applicable taxes and government-
mandated charges for the comparable new 
replacement tire at the time of adjustment. If 
the price of the new comparable tire is $80, 
the cost to you would be $40 plus F.E.T. (U.S. 
only) plus any other applicable taxes and 
government-mandated charges.
WHAT IS A COMPARABLE TIRE?
A “comparable” new Goodyear or Dunlop tire 
will be the same brand tire and may either be 
the same line of tire or, in the event that the 
(Continued on next page) 

29
tire is not available, the same brand tire with 
the same basic construction and quality with 
a different sidewall or tread configuration. If a 
higher priced tire is accepted as replacement, 
the difference in price will be at an additional 
charge to you. 
Any replacement tire provided pursuant to 
this warranty will be covered by the Goodyear 
or Dunlop warranty in effect at the time of 
replacement.
ADDITIONAL PROVISIONS
A tire has delivered its full original tread life and 
the coverage of this limited warranty ends when 
the treadwear indicators become visible (worn 
to 2/32”), or six (6) years from the date of new 
tire purchase, whichever occurs first. (Without 
proof of purchase the date of manufacture will 
be used to determine eligibility.)
LIMITATIONS
This limited warranty is applicable only in the 
United States and Canada.
WHAT IS NOT COVERED BY THIS 
WARRANTY?
This limited warranty does not cover the 
following:
• Tires submitted for ride disturbance complaints that are worn beyond the first 
two thirty-seconds of an inch (2/32”) tread 
depth or tires submitted for ride disturbance 
due to damaged wheels or any vehicle 
condition. • Goodyear & Dunlop do not warrant or give 
credit in any adjustment transaction for any 
kind of material added to a tire (e.g., tire 
fillers, sealants, balancing substances) after 
the tire leaves a factory producing Goodyear 
or Dunlop tires, nor will it adjust any tire that 
has failed as a result of adding such material.
• Irregular wear or damage due to mechanical  condition of the vehicle, improper 
inflation, overloading, high speed spin-up, 
misapplication, misuse, negligence, racing, 
use of tire chains, improper mounting or 
demounting, improper repair, wreck, collision 
or fire.
• Road hazards (includes, but not limited to,  punctures, cuts, snags, impact breaks, etc.).
• Any tire that, after leaving a factory  producing Goodyear or Dunlop tires, has been 
intentionally altered to change its appearance 
(e.g., white inlay on a black tire or regrooved).
• Tires with weather-cracking that were  purchased more than four (4) years prior to 
presentation for adjustment or, if purchase 
date cannot be verified, manufactured more 
than four years prior to presentation for 
adjustment.
• Tires removed from service due to improper  repairs.
• Temporary spare tires used on vehicles used  in racing and on passenger cars in special 
applications such as police pursuit service.
• Goodyear Unisteel Commercial Radial Light  Truck Tires.  • Loss of time, inconvenience, loss of vehicle 
use, incidental or consequential damages.
 •   Tires supplied as Original Equipment are 
not eligible for any tread life warranty 
consideration.

WHAT ARE YOUR LEGAL RIGHTS?
No Representative or Retailer has authority 
to make any representation, promise, or 
agreement on behalf of Goodyear or Dunlop 
except as stated herein.
Any tire, no matter how well constructed, 
may fail in service or otherwise become 
unserviceable due to conditions beyond 
the control of the manufacturer. Under no 
circumstances is this warranty a representation 
that a tire failure cannot occur.
This warranty gives you specific legal rights 
and you may also have other rights that vary 
from state to state or province to province.
DISCLAIMER: THIS WARRANTY IS IN LIEU 
OF, AND GOODYEAR HEREBY DISCLAIMS, 
ANY AND ALL OTHER WARRANTIES AND 
REPRESENTATIONS, EXPRESS OR IMPLIED, 
INCLUDING WITHOUT LIMITATION ANY 
WARRANTY OF MERCHANTABILITY OR 
FITNESS FOR A PARTICULAR PURPOSE, 
AND NO OTHER WARRANTY OR 
REPRESENTATION OF ANY KIND IS MADE 
BY GOODYEAR OR SHALL BE IMPLIED BY 
LAW.

DO MAINTAIN PROPER INFLATION 
PRESSURE IN YOUR TIRES
Proper inflation pressure is necessary for 
optimum tire performance, safety and fuel 
economy. Check inflation pressures at least 
once a month and before long trips. Use an 
accurate tire pressure gauge. Always check 
pressures when the tires are cold (when the 
vehicle has been driven less than one mile). If 
you must check inflation when the tires are 
hot, add 4 psi (27 kPa) to the recommended 
cold inflation pressure. It is difficult to tell just 
by looking at radial tires whether they are 
underinflated.*
Furthermore, when operating a vehicle 
equipped with radial tires, it is difficult to 
notice when a tire has gone flat or nearly flat 
since the “feel” of the vehicle does not change 
significantly.
Progressive air loss may result from punctures, 
cuts, curbing, impacts or partial bead 
unseating. Some fitment causes for air loss are 
(1) incomplete bead seating, (2) bead tearing 
caused by a machine tool due to insufficient 
lubrication or improper adjustment, (3) leaking 
valve core or rubber valve components should 
be replaced when problems are detected and 
whenever tires are replaced.
Always maintain inflation pressure at the level 
recommended by the vehicle manufacturer as shown on the vehicle placard, vehicle 
certification label or in the vehicle Owner’s 
Manual:
Underinflation is the leading cause of tire 
failure and may result in severe cracking, 
component separation or “blowout.” It reduces 
tire load capacity, allows excessive sidewall 
flexing and increases rolling resistance, 
resulting in heat and mechanical damage. 
Maintaining proper inflation pressure is the 
single most important thing you can do to 
promote tire durability and maximize tread life. 
Overinflation increases stiffness, which may 
deteriorate ride and generate unwanted 
vibration. Overinflation also increases the 
chances of impact damage.
DON’T OVERLOAD YOUR VEHICLE 
OR TIRES
Check your vehicle Owner’s Manual to 
determine the load limits. Overloading your 
vehicle places stress on your tires and other 
critical vehicle components. Overloading a 
vehicle can cause poor handling, increased 
fuel consumption and may cause tire failure. 
Overloading your tires can result in severe 
cracking, component separation or "blowout". 
Never fit your vehicle with new tires that have 
less load capacity than shown on the vehicle 
tire placard and remember that optimum 
rim width is important for proper tire load 
distribution and function. The maximum load capacity stamped on the 
sidewalls of P-Metric & European Metric tires 
is reduced by 10% when used on a light truck, 
utility vehicle or trailer. Never fit P-Metric 
or European Metric tires to light trucks that 
specify LT-type replacement tires.
DON’T SPIN YOUR TIRES 
EXCESSIVELY
Avoid excessive tire spinning when your 
vehicle is stuck in snow, ice, mud or sand. The 
centrifugal forces generated by a free-spinning 
tire/wheel assembly may cause sudden tire 
explosion resulting in vehicle damage and/or 
serious personal injury to you or a bystander. 
Never exceed 35 mph/55 km/h, as indicated 
on your speedometer. Use a gentle backward 
and forward rocking motion to free your 
vehicle for continued driving. Never stand near 
or behind a tire spinning at high speeds. For 
example, while attempting to push a vehicle 
that is stuck or when an on-the-car spin 
balance machine is in use.
DO CHECK YOUR TIRES FOR WEAR
Always remove tires from service when 
they reach two thirty-seconds of an inch 
(2/32) remaining tread depth. All new tires 
have treadwear indicators which appear as 
smooth banks in the tread grooves when they 
wear to the two thirty-seconds of an inch 
(2/32) level. Many wet weather accidents 
result from skidding on bald or nearly bald 
GOODYEAR/DUNLOP TIRE LIMITED WARRANTY
(Continued on next page)*  Evidence of air loss or repeated underinflation always requires expert inspection to determine the source of leakage and tire removal to determine repairability. To avoid injury, NEVER attempt to 
reinflate a tire that has been run severely underinflated. 

37MICHELIN PASSENGER AND LIGHT TRUCK TIRE LIMITED WARRANTY
WHO IS COVERED
The original owner of a Michelin Passenger or 
Light Truck tire which bears the Michelin name 
and complete DOT identification number.
WHAT IS COVERED AND FOR HOW LONG
Michelin Passenger and Light Truck tires, used 
in normal service on the vehicle on which they 
were originally fitted and in accordance with 
the maintenance recommendations and safety 
warnings contained in the owner’s manual 
and in the Important Tire Safety Information 
Section of this booklet, are covered by this 
warranty against defects in workmanship 
and material for the life of the original usable 
tread, or 6 years from the date of purchase, 
whichever comes first. At that time, all 
warranties, express or implied, are terminated. 
The usable tread is the original tread down 
to the level of the tread wear indicators 
- 2/32nds of an inch (1.6mm) of tread 
remaining. Date of purchase is documented by 
new vehicle registration or tire sales invoice. If 
no proof of purchase, coverage will be based 
on date of manufacture.
WHAT IS NOT COVERED
Tires which become unserviceable due to:
• Road hazard injury (e.g., a cut, snag, bruise, impact damage, puncture, whether 
repairable or not);
• Incorrect mounting of the tire, tire/wheel  imbalance, or improper repair; • Underinfation, overinflation, improper 
maintenance or other abuse;
• Mechanical irregularity in the vehicle such as  wheel misalignment resulting in uneven or 
rapid wear;
• Accident, fire, chemical corrosion, tire  alteration, or vandalism;
•  Ozone or weather cracking.
WHAT MICHELIN WILL DO 
PASSENGER AND LIGHT TRUCK TIRES 
A tire which becomes unserviceable due to 
a condition covered by this warranty will be 
replaced with a comparable new Michelin 
tire, free of charge, when 2/32nds of an inch 
(1.6mm) or less of the original tread is worn, 
(or 25% or less, whichever is most beneficial to 
the user) and within 12 months of the date of 
purchase. Mounting and balancing of tires is 
included. The cost of any other service charges 
or applicable taxes are payable by the user. 
When more than 2/32nds of an inch of 
original tread has been worn (or more than 
25%, whichever is most beneficial to the user) 
or after 12 months from date of purchase, the 
user must pay the cost of a comparable new 
Michelin passenger or light truck replacement 
tire on a pro-rata basis. The retailer shall 
determine the charge by multiplying the 
percentage of the original usable tread 
worn by the current actual selling price at 
the adjustment location or the price on the 
current Michelin Base Price List, whichever is 
lower. This List is based on a predetermined  price intended to fairly represent the actual 
selling price of the tire. The cost of mounting, 
balancing and any other service charges or 
applicable taxes are payable by the user.
WHAT THE CONSUMER MUST DO 
When making a claim under the terms of this 
warranty, the consumer must present the tire 
to an authorized Michelin Retailer. To locate 
an Authorized Tire Retailer, check the yellow 
pages under “Tire Retailers - Retail.” 
The vehicle on which the tire was used should 
be available for inspection. 
It is essential that you read and understand the 
safety and maintenance recommendations (see 
Safety Maintenance Information) for your tires.
CONDITIONS AND EXCLUSIONS 
THIS WARRANTY DOES NOT PROVIDE 
COMPENSATION FOR LOSS OF TIME, LOSS 
OF USE OF VEHICLE, INCONVENIENCE 
OR CONSEQUENTIAL DAMAGE. TIRES 
PRESENTED FOR CLAIM REMAIN THE 
PROPERTY OF THE CONSUMER AND 
MICHELIN ACCEPTS NO RESPONSIBILITY 
FOR LOSS OF, OR DAMAGE TO, TIRES 
WHICH ARE IN THE CUSTODY OR 
CONTROL OF A MICHELIN TIRE RETAILER 
FOR THE PURPOSES OF INSPECTION FOR 
WARRANTY ADJUSTMENT. IN THE EVENT 
OF A DISPUTED CLAIM, THE CONSUMER 
MUST MAKE THE TIRE AVAILABLE FOR 
FURTHER INSPECTION.

40CONTINENTAL/GENERAL TIRE LIMITED WARRANTY
(B)     Pro Rata Replacement Policy: 
Passenger/Light Truck Tires
After the "Free Replacement Policy" 
expires (set forth in section 2A), and 
the tire is still within 72 months from 
the date of purchase*, you will pay, on 
a pro rata basis, for a comparable** 
new Continental or General brand 
replacement tire. A tire is eligible for an 
adjustment on a pro rata basis until the 
tread is worn down to the tread wear 
indicators (2/32nds of an inch of tread 
remaining). The tire tread is worn out at 
this point and this Policy ends regardless 
of time period. Owner pays all applicable 
taxes (including F.E.T.), mounting and 
balancing charges. 
Serva-Spare Tires
After the “Free Replacement Policy” 
expires (set forth in section 2A), no 
adjustment will be made.
3. HOW A PRO RATA PRICE IS 
CALCULATED
The replacement tire price will be determined 
by multiplying the percentage of the usable 
tread worn by the Retailers Selling Price 
(excluding all applicable taxes) at the time of 
the adjustment or the Continental/General 
brand current published Adjustment Base  Price, whichever is lower. The usable tread 
is the original tread down to the tread wear 
indicators (2/32nds of an inch of tread 
remaining). The Adjustment Base Price is 
intended to fairly represent a Retailer ’s Selling 
Price for the same or comparable tire.
4. WHAT IS NOT COVERED BY THE 
ADJUSTMENT POLICY 
a.  
The following conditions are not covered:
Road Hazard: Cuts, snags, punctures, bruises 
or impact breaks and any damage caused 
by puncture or tire repair. Ride/Vibration: 
After “Free Replacement Policy” (set forth in 
section 2A) expires. 
Tire Damage or Failure Resulting From 
Improper Operation or Maintenance: Load, 
speed, and inflation practices causing 
excessive operational temperatures to 
exceed the tire capabilities. 
Tire damage (including irregular treadwear) 
or failure resulting from: improper mounting 
or demounting, damaged rim, wheel 
alignment, tire trueing, chain damage, brakes 
or any similar mechanical problem, extreme 
temperature exposure, misuse, negligence, 
and abusive driving such as tire spinning, 
racing or accident damage. Tire failure 
resulting from intentional alterations: such 
as adding a white inlay on a blackwall or 
sealant materials.  Age Conditions: Weather checking/cracking 
coverage is for a maximum period of 48 
months from the date of purchase.
b.   General Exclusions - 
Tire(s) submitted for an adjustment in service 
for longer than 72 months from date of 
purchase*, are not covered by this policy. 
Tire(s) on any vehicle registered and normally 
operated outside the United States and 
Canada are not covered under this Policy. 
For tires on vehicles normally operated 
outside the United States and Canada, see 
the nearest Continental or General Tire 
retailer or distributor for local coverage. 
Tire(s) transferred from the vehicle on which 
they were originally installed are not covered 
under this Policy. 
Company does not offer tread wearout 
coverage up to a predetermined mileage 
under this Policy. Tire(s) used in racing 
related activities or competitive events are 
not covered by this Policy.
THIS LIMITED WARRANTY IS IN LIEU OF 
ALL OTHER WARRANTIES, EXPRESS OR 
IMPLIED, INCLUDING, BUT NOT LIMITED 
TO, WARRANTIES OF MERCHANTABILITY 
OR FITNESS FOR A PARTICULAR PURPOSE. 
NO OTHER WARRANTIES, EXPRESS OR 
IMPLIED, INCLUDING, BUT NOT LIMITED 
TO, WARRANTIES OF MERCHANTABILITY 
(Continued on next page)
* At the time of claim, you need to present your new vehicle registration or new vehicle sales invoice showing date of purchase.  If satisfactory proof-of-purchase date is not provided, the D.O.T. 
certification date of manufacture (tire serial number) will be used.
**   A “comparable” new Continental or General brand tire may be either the same tire line or the same basic construction but with a  different sidewall or tread configuration. If a higher-priced tire is accepted 
as replacement, the owner will pay the difference in price. Any tire replaced under this Policy will be covered by the current  Continental or General Tire Limited Warranty and Adjustment Policy 

45
Certain tire manufacturers speed ratings are 
voided if the tire is repaired. 
Although a tire was properly repaired, internal 
structural damage resulting from the puncture 
may have occurred.
Sometime later the damage may cause the tire 
to be removed from service.
If the tire has a puncture in the tread which 
exceeds 1/4 inch (6mm), the tire must be 
replaced. If any tire has sustained a puncture, 
have the tire inspected internally by a tire 
retailer for possible damage that may have 
occurred.
Improper mounting and inflation procedures 
can cause an explosion of the tire/rim 
assembly. Only specially trained persons should 
perform these tasks. Contact your tire store or 
retailer for assistance.
CAUTION - Never, under any circumstance, 
introduce a flammable substance into a tire.
WHEEL ALIGNMENT AND 
BALANCING
Wheel alignment and balancing are important 
for safety and maximum mileage from your 
tires. Check how your tires are wearing at 
least once a month. If your tires are wearing 
unevenly, such as the inside shoulder of the 
tire wearing faster than the rest of the tread, 
or if you detect excessive vibration, your 
vehicle may be out of alignment or balance. 
These conditions not only shorten the life of 
your tires, but adversely affect the handling characteristics of your vehicle which could 
be dangerous. If you detect irregular wear or 
vibration, have your alignment and balance 
checked immediately. Tires which have been 
run underinflated will show more wear on the 
shoulders than in the center of the tread.
HARD BRAKING
You must inspect your tires after any hard 
braking circumstances or after tires have slid 
on the pavement. This can cause a flat spot in 
a section of the tire tread.
TIRE SPINNING 
Never spin your tires above a speedometer 
reading of 35 mph (55 km/h) if your vehicle 
becomes stuck. The centrifugal force 
generated by the free spinning tire/wheel 
assembly may cause a sudden tire explosion, 
resulting in vehicle damage and/or serious 
personal injury or death. Never allow anyone 
to stand near or behind a tire spinning at high 
speed while attempting to push a vehicle that 
is stuck. When in mud, sand, snow, ice or other 
slippery conditions, do not indulge in excessive 
wheel spin. In such conditions, with automatic 
transmission vehicles, by accelerating the 
engine excessively, it is possible to spin one of 
the drive tires beyond its speed capability. This 
is also true when balancing a drive tire/wheel 
assembly using the engine of the vehicle to 
spin the wheel.
TIRE TREAD 
Tires must be replaced when the depth of 
the tread reaches 2/32 inch (1.6 mm). Tires 
are manufactured with tread wear indicators 
molded into the tire grooves which indicate 
tread wearout. As tires approximate 2/32 inch 
(1.6 mm) wearout, the tread gauge becomes 
thinner and more vulnerable to the effects 
of road hazards. Also, worn tires are more 
subject to hydroplaning, which can cause loss 
of control. Therefore, visual tire inspection 
becomes more crucial as the tires wear out.
WORN TIRES
Never drive on worn tires. Tires should be 
replaced by trained personnel when 2/32nds 
of an inch tread depth remains, as indicated 
by the tread wear indicators molded into the 
tread grooves. In most states, it is illegal to 
drive with less than 2/32nds of an inch of 
tread remaining.
TIRE MIXING
For best performance select tires similar in 
size and load rating to the original equipment 
tires. It is recommended that the same size 
and type of tire be used on all four wheel 
positions. In certain tires, casing ply material 
and ply construction may vary as indicated 
on the sidewall of the tire. When changing 
or replacing tires, it is preferred that all four 
tires are the same construction type (i.e., High 
Performance, All Season, Mud & Snow) and 
construction (Radial or Bias Ply). Before
