1994 GMC Suburban Owner's Manual - Page 314

Wheel Replacement Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your GM dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts, or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure tohave the right wheel, wheel bolts, and wheel nuts for your GM model. NOTICE: The wrong wheel can also cause problems with bearing life, brake cooling, speedometer/odometer calibration, headlight aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis.
