gears vs. tire size

I have an 03 f250 with 37 inch toyo m/t's, I tow a 28 ft nrg trailer and was wondering how to figure out which gear to use to get the truck back to tow like it would stock, or at least close. if I can, I want to go to 38's because I think the truck would have a better stance. now should I do a 4.10 or 4.56 or what? is there some kind of chart to go by or just preference and instinct or what. any info would be great thanks fellas...

that is a good answer.
i agree.

i recommend 4.56 whenever you are going to do 40" or bigger, but since you are going to be towing, i would do the 4.56 and you'd still be good with 38" when you upgrade.
the 4.30 are good for 37-38 no problem if you dont plan on towing a lot.

Tire Question?

I have 2 tires that are going bad and cant afford a new set right now. They are 235/85 r 16 . Can I throw a set of 265/75 r 16 on just to get me by for now? Using the same rim from original tires.
