yeah looking at it again, a 33" tire will probably fit up underneath with about 10-15 psi pulled out. as for the 305s, i haven't tried it, but another guy did and his words: "the 305s needed too much hacking to fit" not a hundred percent sure what that entails, but take it for what you will.

I guess i was just thinking that a couple other people had taken to carrying their 33" spare elsewhere. so, buyer beware and take a look at it.
