I had my shinko 244 installed on the front rim today, 4.60 x 18 size, and it looks good. Cant wait to try it out this weekend, its supposed to rain so it should be fun. I was surprised how wimpy the stock tire is, very thin and soft and flexible. I thought it was a beefy tire as I was running 12 psi or so and slamming into roots on the trails and it did not seem like it was almost flat or anything, but its almost like a bicycle tire! I had the 244 around, so thought I would give it a try, the stock front tire kind of sucks in sand. A real knobby will be the next experiment I guess.
