I have a 2 door Sport, D44 in the back, D30 up front... using Spartan Lockers. I can not speak for 35's yet, for all I have are 33 inch tall tires. But, mine is an automatic, and once I put the Gobi Stealth Rack on top, it was like adding a parachute.
I upgraded to 4.88:1 because I am in Florida, and I do a crap load of highway driving. I bought my Jeep March 21'st and it already has over 17k miles on it.
The difference between 3.73 and 4.88 are NIGHT AND DAY. I can't begin to tell you how different it drives and feels. It is like I gained 100 cubic inches... and the converter stays locked. I can actually accellerate while in overdrive! Even with the roof rack.
Now, what would the difference betwen my gears and a 5.13? I can't say. But, my jeep has tons more "feel" to it now, than when it did factory, with the little donuts on it. So, I'm confident I could ride on 35's with no issues.
I was concerned on the small pinion in a D30 so I went with a 4.88. It was my choice, and I don't regret it.
Oh, I'm also in Florida, so it's really flat. I don't tow either... so, that's something to consider.
