4:10s would be fine for 35s, but I'd probably go with 4.56. For 37s, I wouldn't go any higher than 4.56, lower would be better.

I put 4.56 gears in my truck with 305-70-18 tire. Basically a 34" tire. Truck loves it i run 2300 rpm at 75 mph. I would put 4.88s in with a 37. Thats alot of tire to turn.4:10s would be fine for 35s, but I'd probably go with 4.56. For 37s, I wouldn't go any higher than 4.56, lower would be better.
