ive got 22's on my 97 GTP right now, no lift, no rub. the best size ive seen and its what ive got on is a 245/30/22. anything wider will stick out, and anything bigger will rub. ive also got the F-Body brake upgrade and its a world of difference. best thing to do is when you want to put those rims on, upgrading the brakes is a must.
