I drive a 2008 S80 3.2, currently w/18 " Venator wheels/245-40-18 tires. One is terribly bent, thanks to a Michigan pothole. I found a killer deal on a super clean set of 17" Tethys with tires. The set can be had for less than one reconditioned Venator 18". I am wondering if switching to the Tethys will cause any issues, or if it is even feasible ?? My S80 is all stock (OEM brakes). Any info would be greatly appreciated.
