I'm now ready to buy tires for my Jeep. I am thinking about getting 33s .1250-15s. I have a 1997 Wrangler TJ will I be able to put these on this vehicle with out a body lift? If I need to do a body lift how many in. and what kind of body lift kit do I buy. Whats with the hockey pucks... Do they work?? Thanks Nick aka stubs
