I went back and forth a hundred times when I was getting my new wheels and tires about 6 weeks ago. 35's or 37's....got a headache over it once just reading up on what CAN be done vs what SHOULD be done for 37's.
I decided that I would do 35's now(got the MT/R's, there killer), wheel it and work on my build over time to do 37's right, if I really feel the need at all.
I recently re-geared to 5.38 and added the C gussets, and have some RK stuff coming to replace my saggy and sucky 3.5" rough country crap. I'll do other things as I find deals.
I'm pleased with my choice so far, it wheels real nice on the 35's.
Just my 2 cents.
