Anyone put larger rear tires on to increase ground clearance? If so how much is gearing affected? It looks like you could go up to a 25 inch with the 9 inch rim. Just curious I do alot of moutain riding and my chain gaurd wont clear anything!

 

the gearing will change drastically with those tires. really the tallest i see around here is 22's. that to me even looks like crap since the tires are big. but i guess looks doesn't matter, and ground clearance does. you will want to change gearing with these taller tires.
