Tire Extenders
This may be a dumb question but because the tires have to be checked regularly why wouldn't the extenders come standard on the tires from the manufactory?
Forum Discussion
I have asked the same question for years. Since there are safety issues involving use of cheap screw-on extenders, you'd think that chassis and/or house box makers would add solid metal custom formed valve stems to motorhome wheels as standard operating procedure. There must be some deep dark mystery.
