i have a fabtech 6 in lift on an 01 f150 and was wondering if i put on a 3 inch body lift what would be the biggest tire i could fit

 

If it's a 4x4, you could fit 37x12.50's or larger.

 

the absolute largest you could fit would be a 38" 15.5" but you would have to do a few other things like crank your torsion bars all the way and to some cutting of the fronf valance and a small metal nubs on each side of your lower control arms and make a new bracket for your e brake cable on the rear driverside or zip tie it out of the way it will still rub alittle offroading with the wheels turned on the outer rear of the front fenderwell but nothing bad
