![]() ![]() It was a small detail, but a critical one. After returning home, I removed the shiny wheel trim ring and discovered that the tire shop had not properly installed the extension and crushed it against the wheel causing it to leak. Checking my pressures during a subsequent trip, I found the inside dual leaking again. We couldn't find a set of new extensions at any of the RV suppliers, so we ordered them and the tire shop installed all four, figuring that if one was leaking it was time to replace them all. A local tire shop who handles trucks and motorhomes checked and found that it was the extension that was leaking where it had a pretty sharp bend and was touching the steel wheel. ![]() Last year I noticed the RH inside dual was low everytime I checked, losing about 5 psi per day and I thought it might be time to replace the tires. I check the pressure before every trip and until last year had no issues. ![]() Our coach (2001 Aerbus 3550 BSL) had the braided stainless valve stem extensions on it when we bought it in 2004. There are rubber 'grommets' that install in the holes in the outside wheel that support the weight of the stem at high speeds. You could displace enough sealant to clog the valve core seal. Of the extension just because it's easier. Do Not attempt to put the sealant into the threads Apply a SMALL amount of paste thread sealant to the inside valve stem threads. I want to make two points if you must do this.ġ. Bend the stem until you can safely thread the sensor on.Ī tire monitoring system allows you to electronically check pressures, you probably will not have to remove and re-install the sensor more than a couple times a year, if that.įor those of you who do not have a tire monitoring system, I suggest you install, 4" long SOLID metal extensions on the If it is not lined up well enough to ensure against cross-threading, take a piece of 3/8" copper tubing (or equivalent) about a foot longĪnd slide it over the inside stem. If it is, proceed to thread the sensor in place. Note: Before attempting to thread the sensor on to the inside stem, check to make sure the valve stem is "looking" straight When properly tightened, wiggle the extension side to side to loosen its grip on the sensor and remove. Insert the socket w/sensor through the hole in the outside dually and thread the sensor in place.ĥ. Press the sensor lightly into the socket.Ĥ. The solution for accessing the inside dually, for many tire monitoring system, is simple.ģ. When tire maintenance was performed on truck running gear, it didn't matter which wheel went on the inside or outside. The reason the valve stems are positioned toward the wheel mating surface comes from the trucking industry.Īll wheels on semi-trailers and on older tractors are the same. Use a soap solution to ensure there is no leakage. Loosen the nut securing the valve stem in the wheel.Ģ. The solution to easily accessing the outside dual wheel valve stem is:ġ. They're a source of leaks, and it's not IF but WHEN. Now have 166,000+ miles on my 94 Bounder.įirst, I have solutions for accessibility to dual wheel valve stems. I use the valve caps that you do not remove for testing. What can you tell me about what to do about this? I feel that especially with the rear tires, I have to insure that I monitor the pressure, as I could easily have a leak or flat in a rear inside tire and probably not even notice it 'til the outside tire blew.Īfter having problems with the pressurized braided estensions, I went with the solid unpressurized extensions with no more problems. Even tire stores are reluctant to install extensions it seems. I'm receiving alot of free advice, from don't install them to only use straight extensions on the inside wheels. I purchased a tire pressure monitoring system then quickly realized that access to the valves on the rear four wheels was obstructed.that the outside rear tire stems pointed inward, and the inside rear tire stems could not be reached. In.Being new to RVing, one of my concerns has been maintenance of the tires and in particular, how to monitor the tire pressure. V6 GAS DOHC Naturally Aspiratedģ.6L 3564CC 217Cu.
