Information on P Type Tires
P215/65R15 95H is an example of
a tire size, load index and speedrating. The definitions of theseitems are listed below. (Note thatthe tire size, load index and speedrating for your vehicle may bedifferent from this example.)
A.P: Indicates a tire, designatedby the Tire and Rim Association,that may be used for service oncars, sport utility vehicles,minivans and light trucks.Note: Ifyour tire size does not begin witha letter this may mean it isdesignated by either the EuropeanTire and Rim TechnicalOrganization or the Japan TireManufacturing Association.
B.215: Indicates the nominalwidth of the tire in millimetersfrom sidewall edge to sidewalledge. In general, the larger thenumber, the wider the tire.
C.65: Indicates the aspect ratiowhich gives the tire's ratio ofheight to width.
D.R: Indicates a radial type tire.
E.15: Indicates the wheel or rimdiameter in inches. If you changeyour wheel size, you will have topurchase new tires to match thenew wheel diameter.
F.95: Indicates the tire's loadindex. It is an index that relates tohow much weight a tire can carry.You may find this information inyour owner’s manual. If not,contact a local tire dealer.
Note:You may not find thisinformation on all tires because itis not required by federal law.
G.H: Indicates the tire's speedrating. The speed rating denotesthe speed at which a tire isdesigned to be driven for extendedperiods of time under a standardcondition of load and inflationpressure. The tires on your vehiclemay operate at differentconditions for load and inflationpressure. These speed ratings mayneed to be adjusted for thedifference in conditions. Theratings range from 81 mph(130 km/h) to 186 mph
(299 km/h). These ratings arelisted in the following chart.

C.80: Indicates the aspect ratiowhich gives the tire's ratio ofheight to width. Numbers of 70 orlower indicate a short sidewall.
D.D: Indicates a diagonal type tire.
R: Indicates a radial type tire.
E.16: Indicates the wheel or rimdiameter in inches. If you changeyour wheel size, you will have topurchase new tires to match thenew wheel diameter.
GLOSSARY OF TIRE
TERMINOLOGY
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) andfor Metric tires 36 psi (2.5 bar).Increasing the inflation pressurebeyond this pressure will not
increase the tire’s load carryingcapability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.
*kPa: Kilopascal, a metric unit ofair pressure.
*PSI: Pounds per square inch, astandard unit of air pressure.
*Cold tire pressure: The tirepressure when the vehicle hasbeen stationary and out of directsunlight for an hour or more andprior to the vehicle being driven for1 mi (1.6 km).
*Recommended inflationpressure: The cold inflationpressure found on the SafetyCompliance Certification Label(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or Tire Label located onthe B-Pillar or the edge of thedriver door.
* B-pillar: The structural memberat the side of the vehicle behindthe front door.
*Bead area of the tire: Area ofthe tire next to the rim.
* Sidewall of the tire: Areabetween the bead area and thetread.

INSPECTING THE TIRE FOR
WEAR
When the tread is worn down toone sixteenth of an inch (2 mm),tires must be replaced to helpprevent your vehicle from skiddingand hydroplaning. Built-intreadwear indicators, or wear bars,which look like narrow strips ofsmooth rubber across the treadwill appear on the tire when thetread is worn down to onesixteenth of an inch (2 mm).
When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves.
INSPECTING THE TIRE FOR
DAMAGE
Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredismounted and inspected in caseit needs to be repaired or replaced.For your safety, tires that aredamaged or show signs ofexcessive wear should not be usedbecause they are more likely toblow out or fail.
Periodically inspect the tire treadsand sidewalls for damage, suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread or sidewall.If damage is observed orsuspected, have the tire inspectedby a tire professional.
Safety Practices
WARNING: If your vehicleis stuck in snow, mud or sand, donot rapidly spin the tires;spinning the tires can tear thetire and cause an explosion. Atire can explode in as little as
three to five seconds.
WARNING: Do not spin thewheels at over 34 mph(55 km/h). The tires may fail andinjure a passenger or bystander.
