FREQUENTLY ASKED QUESTIONS
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.
1. DEPARTMENT OF TRANSPORTATION (DOT)
The DOT code indicates that the tire is compliant 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.
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.
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.
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.
