I've got a Fisher Marlin '06 and have recently been taking it on some heavy duty single-tracks, jumps, and what not (not the best idea for a XC, I know). I've recently noticed that the tires seemed to be slightly warped, meaning when the tires rotate the wheel seems to wobble right and left. It's a very small wobble (I'd say about a couple cm if I had to guess). My question is, is this a big problem I need to worry about and if so are their anyways I can repair the tires? I'm fairly new at repairing bikes, but am quick and willing to learn. Thanks in advance.
