Ok well the debate for tires is now over. I have a roomate who has a 1999 Ford Ranger XLT 4wd. He has 245/75/16 BFG Rugged Trail tires with a good 20-30k left on them and I have 235/75/15 BFG Long Trails on my 1999 Explorer XLT 4wd. WELL I talked to him jokingly about swapping them out, I wanted bigger tires anyways and rims couldn't hurt either. My rims are in better shape but I am sure I can clean these up, plus there bigger and between the increase in wheel size and the tire size I think there equivilant to 31's maybe so for $100 and my rims and tires I got rid of my weaker less expensive tires and rims for his. Should I do the shackle and TT with this set up or are they not big enough?
