I am running 245/40/18 and 275/40/18 on 18x8/18x9.5. The approximate fender lip to ground measurements are 24.5f and 25.2r. Fronts rub when turning in parking lots a little. I've pushed it pretty hard on a twisty road with no contact issues. Rear tail pipe routing may be an issue, my 2,5" pipes needed to be flatted aproximately .75". Pan head bolts and a little metal massaging should neutralize it. Stock A-arms, lowered coils and leafs, 1" blocks in leafs. Pinion angle went downward 2*.
