Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicle Load Precautions
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.
Rims and wheels are designed to sustain their rated load using the maximum tire size recommended for that rim width by the Tire and Rim Association.
Loading vehicles beyond tire load capacity decreases tire life, requiring more frequent replacement of tires.
The load carrying requirements of each vehicle should be determined before selecting the correct tire/ wheel combination. Always remember that the weakest weight carrying component of the vehicle (tire, wheel, axle, bearings, etc.) determines the overall maximum and safe load carrying capacity for the vehicle.
Never attempt to short-cut the above procedures.
