Thanks to suggestions from the board, I just had a new set of Potenza RE-730’s mounted on 16” BMW Double Spoke Sport Rims for my 98’ 323is. I got the rims off eBay and the tires from Tire Rack. The installer called me saying one rim was bent. It was not obvious to me when I cleaned them. Is there any tell-tell marks left on a rim after they are straightened?? He’s a good mechanic but for some reason I’m having some doubts about whether a rim really needed straightened. Any ideas???
