A couple of weeks ago, I dismounted a tire from a cast aluminum rim that had a very slow leak around the bead. I marked the tire on the rim in regards to balance weights and valve stem. The rim showed some pitting/corrosion on the mating surfaces. I cleaned the rim with a wire wheel and used a rim sealant on it to help seal it. Since I did that, the car pulls to the side away from that tire. Yesterday I swapped front tires from left to right and now it pulls right instead of left. I probably didn't get the tire oriented perfectly to what it had been. Could a little balance problem cause the tire to pull?
