I have the stock 31"s on my 94 SR, thinking about 33"s how much difference will I see with the larger size, thinking of some form of mud tires for crawling around in death valley, some really rough roads/trails, and crawling over the really rough stuff, washouts and boulders in the roads, not quite what most would call rock crawling, but crawling over rocks... Suspension is stock as well. I guess what I'm wondering is what it will effect, and how much.
