Which size tire should I run?

I’d either regear it to 4.88 for the 33’s or go back to 30x9.5. 4.88 and 33 would be a lot better torque wise than 30’s and 3.73 though.

Awesome, good to know. Yeah, 5th gear is pretty much null and void at the moment.

I live on the bay on the south shore of Long Island. There is bridge that spans from the south shore across the bay to the barrier island. It's about a mile or so and is a steep incline both ways to the peak in the middle. I can drop 'er in fifth at 40 and give it gas and it will pull decently hard all the way up that incline. If I did that with 3.73's I probably would have gone backwards.

I have 33s with 3.73 gears and I plan on re-gearing to 4.10s

Don't waste your time & money on 4.10s.
