Default What gear ratio for 33.5" tires?

Its still got the 3.73's in it with a tune and its a dog to get those big tires moving in first. 4.10's? or you think 4.30's? its 5.3. And 4x4. also what size for the front and rear diffs? Just getting all facts straight before hand

4.56 if you are towing a lot, if it's a highway truck, 4.10's.

What about 35's? I do mostly city driving but sometimes do the freeway.

I would probably lean towards a 4.88 if I was running 35's and mostly in town, again, especially if towing.
