9-66 Vehicle Care 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 9‑57. Your vehicle's original equipment tires are listed on the Tire and Loading Information Label. See Vehicle Load Limits on page 8‑12 , for more information about the Tire and Loading Information Label and its location on your vehicle. Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this could affect the way your vehicle performs, including its braking, ride and handling characteristics, stability, and resistance to rollover. Additionally, if your vehicle has electronic systems such as anti‐lock brakes, rollover airbags, traction control, and electronic stability control, the performance of these systems can be affected. { WARNING If you add different sized wheels, your vehicle may not provide an acceptable level of performance and safety if tires not recommended for those wheels are selected. You may increase the chance that you will crash and suffer serious injury. Only use GM specific wheel and tire systems developed for your vehicle, and have them properly installed by a GM certified technician. See Buying New Tires on page 9‑64 and Accessories and Modifications on page 9‑3 for additional information.
