tire growth question

im getting ready to trim my outlaw fiat body for tire growth how much clearance do i need so the tires dont rub at max tire growth i have plenty except in front of the tire hoosier 34.5x17x16 c-2055 thanks jim

 

Jim.....we run 3.5"-4" on our altered with those tires....seems to work pretty well for us. 3.5 is a little on the close side according to the cam-corder. hope this helps
