I´ve never done it to a Jeep, but did have a 3/4 ton Dodge with 36´s and 4.11 gears. Was kind of a dog in low gear, wouldn´t run right, at less than about 1800-2000 RPM (peak torque 2200) and I´m pretty sure you could forget about high gear. Another thing was, when I´d want to stop that thing, from highway speeds, I often felt like I wanted an anchor with me to throw out (forget about panic stops). 3/4 ton brakes where pretty HD but not really up to the job. Finally changed to 33´s 15.50 TSL´s, ran just fine, and pulled a whole lot better in low.[addsig]

Jeepgod.com and 4lo.com have some decent tables that might help you out. A rule of thumb, that seems to work out pretty close, is one gear set, for every two inches over stock. 3.73´s or 4.11´s seem to work well with a 31 inch tire. The ideal ratios from my reconing, falls somewhere between 4.56 and 4.88.
Maybe someone who has a bob tail with 35´s could help you out more.[addsig]

I'm running 4:10's with 33" BFG MT's and my max top speed is 63 MPH. With 35' I'll get my top speed back (65 to 70MPH easy). My tire's are brand new, so I'll be swapping out the 4:10's for 3:73's. Running 4:10 with 35"s you'll feel under powered, and loose a lot in your 4lo crawl.
