Is it worth trying to clean up my rusted rims, or should I just by new ones? The inside of the rims have a little bit of pitting, and even after cleaning up with a wire wheel, there's still some bumpiness to the surface. I don't know how well a tire will seal against the rims. Also, I have 2 6.50 x 16 rims, and 2 7.00 x 15 rims. I don't think the truck (38 half ton) would have come with two different tire sizes, would it?
