Tire Description: Notes

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

Passenger (P) Tires are for vehicles that are designed for personal use such as hatchbacks, sedans, coupes, and crossovers. Many SUVs, minivans, and smaller pickup trucks (typically under 3/4 ton) also use passenger-rated tires.

If a tire does not have a "P" or another letter in front of the numbers, it is considered a "Euro-metric" tire. A Euro-metric tire conforms to the European tire specifications, and often carries a different load index than a comparably sized P-metric tire.

Vehicles such as 3/4 ton or larger pickup trucks, work vans, and other large vehicles that regularly carry heavy loads or pull heavy trailers might use Light Truck (LT) tires. These tires are designed differently than Passenger Tires. LT tires are designed to handle additional weight.

It's critical to ensure the tire's load carrying capacity is sufficient for the vehicle's weight, including any cargo.

Replacement tires should be of the same Tire Performance Criteria (TPC) specification number. This will ensure the same size, the same load range, and the same construction as those originally installed on the vehicle.

GM recommends that tires, including the spare if equipped, be replaced after six years, regardless of tread wear. To identify the age of the tires, use the tire manufacture date which is the last four digits of the DOT Tire Identification Number (TIN) which is molded into one side of the tire sidewall. 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.
