{ WARNING: If you use bias-ply tires on the vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on the vehicle. If you must replace your vehicle's tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias‐belted tires) as your vehicle's original tires. Vehicles that have a tire pressure monitoring system could give an inaccurate low‐pressure warning if non‐TPC Spec rated tires are installed on your vehicle. Non‐TPC Spec rated tires may give a low‐pressure warning that is higher or lower than the proper warning level you would get with TPC Spec rated tires. See Tire Pressure Monitor System on page 6‑66. Your vehicle's original equipment tires are listed on the Tire and Loading Information Label. See Loading the Vehicle on page 5‑19, for more information about the Tire and Loading Information Label and its location on your vehicle. 6-75
