Rotated all 4 tires and rims today and guess what??? 3 of the 4 rims were RUSTED or welded as I would call it , on the car . Even a 5 pound hammer would not loosen the rims from the car. Had to drive the car around the neiborhood with the lug nuts loose to get the rims unstuck .THAT worked !!! The inside of the rim by the lug holes were rusted badly. So when reinstalling them I used wheel grease to coat the inside of the rim area by the lug holes and the lug bolts also . Thank goodness I never had a flat tire on the road as I never would of been able to switch to a spare !!! The unreal thing is that the wheels were taken off only a year ago and they were that badly rusted on the car . NOW my paper-thin rotors ... that is a whole different story !!!!
