Hey guys ,have been noticing an odd feeling from my rear wheel lately and wonder if someone might be able to tell me what the problem could be. At times, It feels like my rear tire is flat or that I'm running along some kind of ruts. I've pulled of the highway, expecting to see a low tire, but it's fine. I've also noticed this sudden wobble when i'm leaning into a turn. I've been told in the past that my rear tire is just slightly out of true. Could that be it, or do you think that it's something else? FYI, It's a new tire so know that there's nothing with the tread.
