I just got a set of race take-offs put on my bike a few days ago, and i've noticed after getting them on the bike pulls to the left a bit. It did not do this with the previous tires. Could this be caused by the left side being worn more (the track is 8 lefts and 2 rights)? I've checked the rear tire and the marks line up perfect. To my knowledge the front tire is on straight when looking at it.
