A lot depends on how you drive, and what speed your typical four wheeling is at. If you drive real slow and careful you will likely be fine with 35s. If you cover 100+ miles a day in the desert on a typical day of four wheeling, you will likely bend the front axle even with stock tires on your Jeep (seen it happen). If you're hitting the bump stops, reinforce the axle.
