For anyone that has a T-1000 or T-720 might want to be careful if you are looking to replace the tires. I tried to upgrade to a generic knobby 26x4 and it wouldn't clear the back of the frame. I'm hoping a 26x3.8 will work but choices are limited. Ideally you would use a 26x3.5, but those in knobbys are even harder to find. If anyone has experienced the same thing and has a possible solution, please let me know.
Cheers
