my bike is less than a week old and when I was cleaning it today, I noticed a bit of wobble on my rear tire, could this have been the result of some trail riding with semi slick tires? (I lowered the pressure to the lowest recommended pressure on the side wall of the tire) or perhaps running over some medium/large potholes during road construction? anywho, what should my next step be? bring it to the LBS for a fix, or attempt to true the tire myself?
