The valve stem hole in my wheels are near the edge of the rim. Is the valve stem in this tube offset from the center of the tube?

Yes. That was the first thing I looked at when I pulled the tubes out of their boxes. Install may be a little easier if you use a valve stem extension. Can/could help to hold the valve in place while you pry the tire bead over the wheel. First one I installed, the valve slipped back through the valve hole in the wheel.

The valve stem hole in my wheels is near the edge of the rim also and it worked fine. The valve stem is offset on the tube.

will this fit in a 22.5x10-8 tire

ProductExpert7· 6 years ago
This is designed to fit just the 20 x 10-8 tire size. At this time, we do not offer an inner tube for a 22.5 x 10-8 tire.
