they were so bad , pro 275, I thought something was coming off the car - probably a wheel .like you I never balancing the rears . the pro275 needed something close to 200grams to get close . MT were good and took them back as faulty . with the pro bracket I barely have 28 grams to balance ( 1 ounce). I only balanced these to get a comparison . have never balanced or checked the hoosier radial .
hoosiers are very forgiving , I hope I can get a bit more life with the MT though . also hoping the new 10" rim I ordered will help the lifespan
hey belvedere do you have the stock rear width differential under your 65 ? tubbed ? what backspace rim ?
