Just like with most old trucks, running 35s is no small task. You will need to rehear, have at least 4 inches of lift and do something to strengthen the axles as the 35s add a lot of weight.
Once all the peripherals are done I would imagine it would run OK. The 4.0 is a powerful engine and the TJ a very small truck. That being said, it will definatelly be much slower than stock
