UTQGS (Uniform Tire Quality Grading

Standards): A tire information system that

provides consumers with ratings for a tire’s

traction, temperature, and treadwear. Ratings are

determined by tire manufacturers using

government testing procedures. The ratings are

molded into the sidewall of the tire. See Uniform

Tire Quality Grading on page 453.

Vehicle Capacity Weight: The number of

designated seating positions multiplied by 150 lbs

(68 kg) plus the rated cargo load. See Loading

Your Vehicle on page 361.

Vehicle Maximum Load on the Tire: Load on an

individual tire due to curb weight, accessory

weight, occupant weight, and cargo weight.

Vehicle Placard: A label permanently attached to

a vehicle showing the vehicle’s capacity weight

and the original equipment tire size and

recommended inﬂation pressure. See “Tire and

Loading Information Label” under Loading

Your Vehicle on page 361.

Inﬂation - Tire Pressure

Tires need the correct amount of air pressure to

operate effectively.

Notice: Do not let anyone tell you that

under-inﬂation or over-inﬂation is all right.

It is not. If your tires do not have enough air

(under-inﬂation), you can get the following:

• Too much ﬂexing

• Too much heat

• Tire overloading

• Premature or irregular wear

• Poor handling

• Reduced fuel economy

If your tires have too much air (over-inﬂation),

you can get the following:

• Unusual wear

• Poor handling

• Rough ride

• Needless damage from road hazards
