Hey guys, new to the forum and have a question. I purchased a big wheel kit and have noticed a problem. Once gaining some speed the bike appears to wobble. I've already had to send the front right tire back because it would not hold air and am hoping that I don't need to send the others back (bought them from a guy online and he's a pain to deal with....my mistake- should have sucked it up but I didn't know it would make a difference on tires). I believe it's one of the rear tires, can I have them remounted to solve the problem? Any help would be appreciated!
