I have searched a lot for my question but I am still not sure.. So.. I'm going to just ask.. I am looking to get new tires for my OEM 19s.. And I didn't want to drop my car at all.. And I like to fill up that gap between the fender and the tires.. Will it be ok to get 245/40 and 255/40?? I know it's gonna mess up my Speedometer.. But there won't be any issues except that right? I also got 15/20 mm spacers for the OEM.. Will they be ok with spacers?? Thanks..
