I've noticed that after 10 or 20 miles the valve stem will start to point at a angle, indicating that the inner tube valve stem is no longer centered on the valve stem hole in the rim. It would appear that the inner tube is rotating in the same plane as the wheel rotation. I've taken the tire off several times and realigned the inner tube, but after a few rides the stem is at an angle again. Although the problem is most pronounced on my front wheel I can see a similar effect on the rear as well. If I just leave it the angle gets more and more pronounced and I'm afraid there is undue stress on the stem and tube.
Both front and rear are Serfas Drifter Survivor 26x2" tires, with Mr. Tuffy liners and thorn resistant tubes, inflated to 40 psi.
Anyone have any idea what could be causing this and any possible solutions?
Thanks.
