Tire valve extentions

(1/2) > >>

John Padmore:
Had 4 new tires put on the motorhome to bring home for the first time. The shop said the valve extensions on the inner tires were leaking. Does anyone have an outlet for these?  Got home (3 hour ride) and one tire was flat.   >:(

Also, what is the fluid reservoir next to the windshield washer reservoir.....brake fluid? Thanks...

Camping World has various extension types, and there are many options on Amazon.com (be sure to access Amazon off the main Beaver Ambassodor Club website).  The better ones are metal or metal sheathed.

Can't answer your second question as we have a different coach model/year, but I'm sure someone here knows.

John,

Driving just a short distance with an RV or large truck tire that is low will ruin it. The steel wire wound cables in the sidewall are designed to flex as the tire meets the road but there is a tolerance to that flex angle set by the inflation level. When the tire is low the flex angle gets more severe. When you bend steel back and forth too severely it weakens it and it will break. Those cables hold the tire together. If it was a front tire without question I would get it changed and if it was a rear I would have both of the tires on that side at least pulled and closely inspected. The tire shop should have never put you back on the road with that issue. This is an example of some failed cables (below) in the sidewall of my RV tire that had never been under inflated but had a different cause of fail. A fail like this in the industry is referred to as a zipper fail. At these tire pressures the cables are required to hold the tire together. I'm not trying to be an alarmist here, just wanting you and your family to be safe on the road.

Car tires and small truck tires do not have this issue nearly to the extent of an RV tire because steel cables are not needed in the sidewall. The rubber will tolerate more flexing without failing.

Classic Zipper Blow Out makes a large boom. I had one at 60 mph and the guy in a delivery truck that was passing me stopped and checked his tires.

John Padmore:
Thanks for the heads up, I appreciate it. I was going to have the valve looked at but now will take your advice and have them checked.
