If I wanted to do light, nicely manicured wimpy trails, what's the biggest/best tire I could fit between those front brakes? And would I need wider rims for such a thing? Again, doesn't need to be an all out downhill mountain bike tire....just some light offroad duty.
Like the other poster said, 28's are prolly the biggest you are going to get away with. That's doing well. 25's are the absolute biggest that will fit in
'LLRRH's fork. Those are 23's in there now. I would take her on a 'nicely manicured, wimpy trail'. It just means paying close attention to what is on the ground. Back to you, those rims are wide enough for anything you could fit in the fork. That is the case with most bikes, even ones with more opening. You would be shocked at how much range of tire size there is for a
given rim, and people routinely exceed manufacturers conservative limits without consequences.
