well i have a 2003 honda rancher 350 tm with 25`s on it at the moment and was wondering if i can gobigger maybe 27`s? I ride in muddy conditions like ponds and creeks.

 

27's mite be pushing it without a lift. MABE 26's. but you've gota remember the lug size on your tires is gona be more than stock. meaning your tires mite b more than 26 inches in diameter. you can try takeing a tape measure from the center of your rear hub to the front of your rear plastic fender, if its 13.5 inches or less no way 27's will fit.

if your just mudding then go for 25's or 26's with big lugs and an agressive tread
