ON CERTAIN PASSENGER VEHICLES, IF AN OWNER CHANGES THEIR WHEELS/TIRES BETWEEN SUMMER AND WINTER USING A STEEL WHEEL IN THE WINTER AND AN ALLOY WHEEL IN THE SUMMER, IT IS POSSIBLE FOR RUST AND CONTAMINATION TO BUILD UP ON THE WHEEL HUB DURING THE STEEL WHEEL USAGE. IF THIS OCCURS AND THE CONTAMINATION IS NOT REMOVED, IT IS POSSIBLE THAT AFTER THE TIRE CHANGE SERVICE, SOME OF THIS CONTAMINATION COULD FLAKE OR GRIND AWAY RESULTING IN REDUCED CLAMPING FORCE OF THE WHEEL TO THE HUB. OVER SEVERAL SEASONS, IT IS POSSIBLE THAT THIS REDUCED FORCE COULD RESULT IN FRACTURES DEVELOPING IN THE WHEEL BOLTS DUE TO WHEEL TO HUB MOVEMENT.
