Here's a pic of the Mudlites, and I agree with Kid, you can go even taller, but you'll need to make some modifications otherwise you're going to lose your low end.

I wanted to keep the stock rims cause I like the way they look (and I was being cheap), so that really limits what you can do, especially on the front. But, I went with a Kenda on the front and it was much, much taller than the stock tire. I did have to relocate the front fender brackets.
