Tire specifications
The following information can be found on a tire's sidewall.
Tire ratings
Speed ratingsThe speed ratings in the table translate as fol- low:
Speed ratings
M81 mph (130 km/h)
Q100 mph (160 km/h)
T118 mph (190 km/h)
H130 mph (210 km/h)
V149 mph (240 km/h)
W168 mph (270 km/h)
Y186 mph (300 km/h)
Information on the sidewall
Federal law mandates that tire manufacturers place standardized information on the side-wall of all tires (see the illustration). The following information is listed on the tire sidewall: The tire designation:
NOTE
Please be aware that the following tire designation is an example only and that
this particular tire may not be available onyour vehicle.
1. 215: the width of the tire (in millimeters)
from sidewall edge to sidewall edge. The larger the number, the wider the tire.
2. 65: The ratio of the tire's height to its
width in percent.
3. R: Radial tire (the designation RF and the
symbol indicate that the vehicle is
equipped with optional self-supporting run flat tires 3
.
4. 15: The diameter of the wheel rim (in
inches).
5. 95: The tire's load index. In this example,
a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maxi-
mum speed at which the tire is designedto be driven for extended periods of time,carrying a permissible load for the vehi-cle, and with correct inflation pressure.For example, H indicates a speed ratingof 130 mph (210 km/h).
NOTE
The tire's load index and speed rating may not appear on the sidewall because theyare not required by law.
3 Self-supporting run flat tires may not be available on all models

• Cold tires
: The tires are considered to be
cold when they have the same tempera-ture as the surrounding (ambient) air. Thistemperature is normally reached after thevehicle has been parked for at least3 hours.Tire specifications – Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETYREQUIREMENTS IN ADDITION TO THESEGRADES .
Quality grades can be found, where appli-cable, on the tire sidewall between thetread shoulder and maximum sectionwidth. For example: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when tes-ted under controlled conditions on a specifiedgovernment test course. For example, a tiregraded 150 would wear one and one half(1 ½) times as well on the government courseas a tire graded 100. The relative perform-ance of tires depends upon the actual condi-tions of their use, however, and many departsignificantly from the norm due to variation indriving habits, maintenance practices and dif-ferences in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest,are AA, A, B, and C, as measured under con-trolled conditions on specified governmenttest surfaces of asphalt and concrete. A tiremarked C may have poor traction perform- ance. The traction grade assigned to this tireis based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance tothe generation of heat and its ability to dissi-pate heat when tested under controlled con-ditions on a specified indoor laboratory testwheel. Sustained high temperature can causethe material of the tire to degenerate andreduce tire life, and excessive temperaturecan lead to sudden tire failure. The grade Ccorresponds to a minimum level of perform-ance that all passenger vehicle tires mustmeet under the Federal Motor Safety Stand-ard No. 109. Grades B and A represent higherlevels of performance on the laboratory testwheel than the minimum required by law.
