I replaced the rear tire and tube on my ttr 230.I installed the tube and whatnot and put the tire back on my bike and i hear tire leaking from the rim lock. What could this be? (P.S. The tire loses air sitting there but loses ALOT more when u ride on it).Im thinking a pinched tube? Oh yeah it also makes noise when you drive the bike andthe rim lock part of the tire is touching the ground.
