275/60's in back and if you want the big 'n sknny look go with 205/75's up front (if your rims are 5-6" wide.) If you want more of an agressive look 235/60's up front on 7" rims look good too. I say 5-6" for 205/75's because any wider rim and the tire gets to distorted in the sidewall area "stretching" out to meet the rim edge.
