Wheels And Tires

WARNING: Do not mix different types of tires, such as radial, bias, or bias-belted, on the same vehicle except in emergencies. Vehicle handling can be seriously affected and can result in loss of control.

Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures.

Tire and Wheel Runout
Excessive radial and lateral runout of a wheel and tire assembly can cause roughness, vibration, wheel tramp, tire wear, and steering wheel tremor.
