I ordered a set of 195/50/15 series tires from tirerack.com for 37 bucks a piece. There for my si wheels that I have on my Integra. I got an e-mail from tirerack and they said that it will mess up my speedometer and it might mess up my brakes. If so how much will the speedometer be off by? Also will it mess up my brakes? Help greatly appreciated.
