Wheels and Tires

Tires
Every new GM vehicle has high-quality tires made by a leading tire manufacturer. See the warranty manual for information regarding the tire warranty and where to get service. For additional information refer to the tire manufacturer.

Warning

1. Poorly maintained and improperly used tires are dangerous.
2. Overloading the tires can cause overheating as a result of too much flexing. There could be a blowout and a serious crash. See Vehicle Load Limits 0 163.
3. Underinflated tires pose the same danger as overloaded tires. The resulting crash could cause serious injury.
   Check all tires frequently to maintain the recommended pressure.
   Tire pressure should be checked when the tires are cold.
4. Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when hitting a pothole.
   Keep tires at the recommended pressure.
5. Worn or old tires can cause a crash. If the tread is badly worn, replace them.
6. Replace any tires that have been damaged by impacts with potholes, curbs, etc.
7. Improperly repaired tires can cause a crash. Only the dealer or an authorized tire service center should repair, replace, dismount, and mount the tires.
8. Do not spin the tires in excess of 56 km/h (35 mph) on slippery surfaces such as snow, mud, ice, etc. Excessive spinning may cause the tires to explode.

All-Season Tires

This vehicle may come with all-season tires. These tires are designed to provide good overall performance on most road surfaces and weather conditions. Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. Original equipment all-season tires can be identified by the last two characters of this TPC code, which will be “MS.”
Consider installing winter tires on the vehicle if frequent driving on snow or ice-covered roads is expected. All-season tires provide adequate performance for most winter driving conditions, but they may not offer the same level of traction or performance as winter tires on snow or ice-covered roads. See Winter Tires 0 244.

Winter Tires
This vehicle was not originally equipped with winter tires. Winter tires are designed for increased traction on snow and ice-covered roads. Consider installing winter tires on the vehicle if frequent driving on ice or snow-covered roads is expected. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires 0 259. With winter tires, there may be decreased dry road traction, increased road noise, and shorter tread life. After changing to winter tires, be alert for changes in vehicle handling and braking.
If using winter tires:

1. Use tires of the same brand and tread type on all four wheel positions.
2. Use only radial ply tires of the same size, load range, and speed rating as the original equipment tires.
   Winter tires with the same speed rating as the original equipment tires may not be available for H, V, W, Y, and ZR speed-rated tires. If winter tires with a lower speed rating are chosen, never exceed the tire’s maximum speed capability.

Low-Profile Tires
If the vehicle has P245/40R19 or 255/35R20 size tires, they are classified as low-profile tires.

Caution
Low-profile tires are more susceptible to damage from road hazards or curb impact than standard-profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like potholes, or sharp-edged objects, or when sliding into a curb. The warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and when possible, avoid contact with
curbs, potholes, and other road hazards.

Summer Tires
This vehicle may come with 255/ 35R20 high-performance summer tires. These tires have a special tread and compound that are optimized for maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates and on ice and snow. It is recommended that winter tires be installed on the vehicle if frequent driving at temperatures below approximately 5 °C (40 °F) or on ice or snow-covered roads is expected. See Winter Tires 0 244.

Caution
High-performance summer tires have rubber compounds that lose flexibility and may develop surface cracks in the tread area at temperatures below −7 °C (20 ° F). Always store high-performance summer tires indoors and at temperatures above −7 °C (20 °F) when not in use. If the tires have been subjected to −7 °C (20 °F) or less, let them warm up in a heated space to at least 5 °C (40 °F) for 24 hours or more before being installed or driving a vehicle on which they are installed. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use. See Tire Inspection 0 257.

Tire Sidewall Labeling
Useful information about a tire is molded into its sidewall. The examples show a typical passenger vehicle tire and a compact spare tire sidewall.

Passenger (P-Metric) Tire Example

1. Tire Size : The tire size is a combination of letters and numbers used to define a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section.
2. TPC Spec (Tire Performance Criteria Specification) : Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines.
3. DOT (Department of Transportation) : The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. DOT Tire Date of Manufacture: The last four digits of the TIN indicate the tire manufactured date. The first two digits represent the week (01–52) and the last two digits, the year. For example, the third week of the year 2010 would have a four-digit DOT date of 0310.
4. Tire Identification Number (TIN) : The letters and numbers following the DOT (Department of Transportation) code are the
   Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture.
5. Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread.
6. Uniform Tire Quality Grading (UTQG) : Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction, and temperature resistance. For more information see Uniform Tire Quality Grading 0 261.
7. Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load.

Tire Designations

Tire Size
The following is an example of a typical passenger vehicle tire size.

1. Passenger (P-Metric) Tire : The United States version of a metric tire sizing system. The letter P as the first character in the tire size means a passenger vehicle tire engineered to standards set by the U.S. Tire and Rim Association.
2. Tire Width: The three-digit number indicates the tire section width in millimeters from sidewall to sidewall.
3. Aspect Ratio : A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 60, as shown in item 3 of the illustration, it would mean that the tire’s sidewall is 60 percent as high as it is wide.
4. Construction Code : A letter code is used to indicate the type of ply construction in the tire.
   The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction.
5. Rim Diameter: Diameter of
   the wheel in inches.
6. Service Description: These characters represent the load index and speed rating of the tire. The load index represents the load-carrying capacity a tire is certified to carry. The speed rating is the maximum speed a tire is certified to carry a load.

Tire Terminology and Definitions

• Air Pressure: The amount of air inside the tire pressing outward on each square inch of the tire. Air pressure is expressed in kPa (kilopascal) or psi (pounds per square inch).
• Accessory Weight: The combined weight of optional accessories. Some examples of optional accessories are automatic transmission, power windows, power seats, and air
  conditioning.
• Aspect Ratio: The relationship of a tire’s height to its width.
• Belt: A rubber-coated layer of cords between the plies and the tread. Cords may be made from steel or other reinforcing materials.
