the OP's post should be a cautionary tale. RTFM folks. with these modern cars, and especially with AWD cars, one can't just go strapping on wheels/tires all willy nilly. the cars ABS, traction control, etc. computers can adjust for about + or - 3 - 5% difference in rolling diameter without adjusting the settings. anythign else and you'll get codes.
