FREQUENTLY ASKED QUESTIONS

HOW DO I KNOW IF MY TIRES NEED REPLACING?

When your tires only have 2/32 of an inch or less of tread remaining, the wear indicators in each tire’s grooves will be level with the outer tread surface. Rubber in tires ages over time. This also applies to the spare tire (if available), even if it is never used. Multiple factors including time, temperature, loading conditions and improper inflation, affect how fast a tire ages.

 

GM recommends that tires, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of a tire, use the tire manufacture date, which is the last four digits of the DOT Tire Identification Number (TIN) molded into one side of the tire sidewall. The last four digits of the TIN indicate the tire manufactured date. The first two digits represent the week and the last two digits, the year. For example, the third week of the year 2020 would have a 4-digit DOT date of 0320. Week 01 is the first full week (Sunday through Saturday) of each year.

 

WARNING SIGNS THAT YOUR VEHICLE WILL NEED TIRE REPLACEMENT:

 

  • The tire tread has worn down to the same level as the wear bars/indicators located in the tread grooves
  • The tire cord or fabric is showing through the rubber
  • The tire tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric
  • Bulge or cracks on tire sidewall
  • Uneven tire wear
  • Flat spots on tire
  • Center of tire is worn
  • The tire has a puncture, cut, or other damage that can’t be repaired correctly

HOW TO READ A TIRE SIDEWALL

How to read the sidewall of a tire

Tire Type The letter "P" at the beginning of the "Tire Size" tells us the tire is a P-Metric tire, referring to tires intended for Passenger vehicles. The letters "LT," would indicate it was designed for light trucks.

Tire Width Tire width is measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P185/60 R14 tire, the width is 185 millimeters.

Aspect Ratio The ratio of the height to width. For example, in a P185/60 R14 tire, the 60 means the height is equal to 60% of the tire's width. The bigger the aspect ratio, the taller the tire's sidewall.

Construction The letter "R" in a tire size stands for Radial, which means the layers run radially across the tire.

Wheel Diameter The size of the wheel the tire is intended to fit. A size P185/60 R14 tire is made for a 14" diameter wheel.
Tire sidewall Department of Transportation code

1. DEPARTMENT OF TRANSPORTATION (DOT)

The DOT code indicates that the tire is in compliance with U.S. Department of Transportation Motor Vehicle Safety Standards.

2. TIRE IDENTIFICATION NUMBER (TIN)

The letters and numbers following the DOT code make up the 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.

3. TIRE PLY MATERIAL

The type of cord and number of plies in the sidewall and under the tread.

4. UNIFORM TIRE QUALITY GRADING (UTQG)

A tire information system that provides consumers with ratings for a tire’s traction (from AA to C) and for temperature (from A to C). Ratings are determined by tire manufacturers using government-prescribed test procedures and are molded into the sidewall of the tire.

5. MAXIMUM COLD INFLATION LOAD LIMIT

This information tells the maximum load that can be carried and the maximum pressure needed to support that load. Find more information on tire pressure and inflation

6. TIRE PERFORMANCE CRITERIA SPECIFICATION (TPC SPEC)

Most OE tires designed to GM’s specific tire performance criteria have a TPC spec code molded onto the sidewall. GM’s TPC specs meet or exceed all federal safety guidelines.

HOW TO MEASURE TREAD DEPTH


Understanding proper tire maintenance, selection and safety for your GMC vehicle starts with knowing the basics. When your tires only have 2/32 of an inch or less of tread remaining, the wear indicators in each tire’s grooves will be level with the outer tread surface. All-season tires have one set of these indicators on each tire. Winter tires will often have two sets of wear indicators: the higher set, which shows the tread level safe for winter driving, and the lower set, which shows the tread level safe for spring, summer and fall usage. Other warning signs include bulges and splits, cracked sidewalls, visible tire cord and punctures. 

Tire wear penny test from GMC Certified Service

THE PENNY TEST

The easiest way to check wear on your GMC vehicle’s tire is with a penny. Place a penny upside down in between the tire tread as shown on the right. If you can see the top of Lincoln’s head, the treads are worn and tire replacement is needed.
