Which tire size

[87toyrunner]

I am going to pickup some new tires this weekend for my 4runner from summit racing. I have decided on BFG MT tread. My question is on size. I think I want to go with 32x11.5-15 or 31x10.5-15. My 4runner is my DD but I also go trail riding about every other weekend. I don't do any rock crawling but I do love to play in the snow and mud. What are the disadvanges and advantages of going with the wider tire? Thanks for any input that anyone has.

I really like my 32s. I had 31s before and the wider tire does better in the mud and looks cooler, they really dont drag the engine down anymore than the 31s did either.
