I think I decided on a set of tires.

Nope. Still not available yet. Now I am wondering if 37" is the best way to go.

I always thought I had 4.11 gears but after using the GPS today to match the speed to the RPM it is evident I have 3.73s. It really comes down to finding a good mix of off road and highway gearing. Right now with these 33" tires I have to give it a good bit of gas to get over obstacles due to the gearing. My highway cruising RPM is pretty good with 2500RPM at 65MPH. If I throw 37" on there my cruising RPM goes to 2200RPm which is even better but there is no way in hell I will be able to turn those tires in front of an obstacle.

So now I have to consider upgrading my gears to 4.11, 4.56, or 4.88.

My limitation is I am not willing to cruise less than 65MPH since this is not a trailer queen and I do not want the engine above 2500RPM for more than an hour or so for trips.

With 37" tires at 65MPH I get the following cruise RPM...
4.88: 2880 RPM
4.56: 2690 RPM
4.11: 2425 RPM
3.73: 2200 RPM

With 35" tires at 65MPH I get the following cruise RPM...
4.88: 3045 RPM
4.56: 2845 RPM
4.11: 2564 RPM
3.73: 2327 RPM

Considering my restrictions of speed and RPM, the two choices are 35" or 37" with 4.11 gears.

Now, I need help to determine which of the two tire sizes will be a better choice using the 4.11 gearing for an off road environment both in terms of gearing and tire height advantage.

If anyone thinks I am completely out of my gord, please say so and show me the light. Right now I am not seeing another option.
