I run 5.29s with 33s with a 3rz. for me it's a trade off. I have single case gearset so my crawl ability is increased in 4low. The real benefit for me is a very usable 4hi for sand and mud. The only drawback is higher rpm's on the freeway which means less mpg's (if I want to go real fast)and the need to shift sooner especially from 1st gear(2wd). If I had dual cases I think 4.88's would be perfect for my 3rz w/33's.
In regards to the original question, I wouldn't even consider anything but 5.29's for 35's and especially 37's for the 3rz unless it's a trailer queen. If you were going with the 3.4 swap, the 4.88/5.29 decision would be more difficult.
A 3RZ, 33s w/5.29s you must be pulling on everybody up the passes. You wheel with a bunch of guys with bigger equipment, do you find you can wheel most everything with 33s or do you feel there's a need for more tire?
I have this theory the we really don't need much more than 33s and I want to hear your take on that with the trails you run.
