Sidewall: portion of a tire between the tread and bead. Section width: the li
near distance between
the exteriors of the sidewalls of aninflated tire, excluding elevations due to labeling, decoration, or protective bands. Bead: the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim. Ply: a layer of rubber-coated parallel cords. Cord: the strands forming the plies in the tire. Rim: a metal support for a tire or a tire and tube assembly upon which the tire beads are seated. Rim diameter: nominal diameter of the bead seat. Groove: the space between two adjacent tread ribs.

EXAMPLE: DOT MA L9 ABCD 1504
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tiregraded 150 would wear one and one-half (11/2) times as well on the government course
as a tire graded 100. The relative performance of tires depends upon the actual conditions oftheir use, however, and may depart signifi- cantly from the norm due to variations in driving habits, service practices and differ-ences in road characteristics and climate. The traction grades, from highest to lowest, are AA, A, B and C. Those grades represent the tire’s ability to stop on wet pavement asmeasured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poortraction performance.
The temperature grades are A (the highest), B and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditionson a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reducetire life, and excessive temperature can lead to sudden tire failure. The grade C corre- sponds to a level of performance which allpassenger car tires must meet under the Fed-eral Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel thanthe minimum required by law.

Proper tire inflation pressure is essential forthe safe and satisfactory operation of your vehicle. The wrong tire pressure will cause problems in three major areas: Safety Too little pressure increases flexing in the tire and can cause tire failure. Too much pressure can cause a tire to lose its abilityto cushion shock. Objects on the road and potholes could then cause tire damage that may result in tire failure.

Economy The wrong tire pressure can cause uneven wear patterns in the tire tread. These abnormal wear patterns will reduce thetread life, and the tire will have to be replaced sooner. Too little pressure also makes it harder forthe tire to roll, and this uses up more fuel. Ride comfort and vehicle stability The superior riding experience built intoyour vehicle partly depends on the correcttire pressure. Too much pressure gives an uncomfortable and jarring ride. Too little pressure feels as if your vehicle is slow torespond. Unequal tire pressures can make steering your vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placard attached to the driver’s door sill. (Refer to “Tire and loading information plac-ard” on page 11-3.) The recommended infl
ation pressures under
normal driving conditions should be used forthe tires listed below.
Tire pressures should be checked, and adjusted if necessary, at least once a month. Pressures should be checked more often whenever weather temperatures changeseverely, because tire pressures change with outdoor temperatures. The pressures listed are always “cold inflation pressure”.Cold inflation pressure is measured after the vehicle has been parked for at least three hours or is driven less than 1 mile (1.6 km)after having been parked for three hours.Cold inflation pressure must not go above the maximum values molded into the tire side- wall. After driving several miles, your tireinflation pressure may increase 2 to 6 psi (14 to 41 kPa) from the cold inflation pressure. Do not let air out of the tires to get back to thespecified cold pressure, or your tires will be too low. Check your tires each time you refuel. If onetire looks lower than the others, check the pressure for all of them. You should also take the following safety pre-cautions:
Keep your tires inflated to the recom- mended pressures. (See the tire and load- ing information placard attached to the driver’s door sill.) Stay within the recommended load limits. Make sure that the weight of any load in your vehicle is evenly distributed. Drive at safe speeds. After filling your tires to the correct pres- sure, check them for damage and airleaks. Be sure to reinstall the caps on thevalve stems.

Replacing tires and wheels
CAUTION Avoid using different si
ze tires from the one
listed and the combined use of different types of tires, as this can affect drivingsafety. Refer to “Tires and wheels” on page 11-7. On all-wheel drive vehicles, always use tires of the same size, same type, and same brand, and which have no wear differences. Usingtires that differ in size, type, brand or the degree of wear, will increase the differential oil temperature, resulting in possible damage to the driving system. Further, the drive train will be subjected to excessive loading, possi-bly leading to oil leakage, component sei- zure, or other serious problems.

This information is provided in compliance with the requirements of the National High-way Traffic Safety Administration, Depart- ment of Transportation. It provides the purchasers and/or prospective purchaserswith information on reporting safety defects. DOT quality grades - All passenger vehicle tires must conform to Federal Safety Require-ments in addition to these grades. The spe- cific grade rating in each grade category is shown on the side wall of the tires on yourvehicle. The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tiregraded 150 would wear one and one-half (11/2) times as well on the government course
as a tire graded 100. The relative performance of tires depends upon the actual conditions of
