Look out for those fancy flexible tire filler hoses.

My 04 Diplomat rear outside tire was flat this morning with the factory installed flexible filler hoses attached. Had the professional tire guy out to find the problem with the tire and he found it was perfectly fine with no holes. The repair man then found the cause of the flat tire. The fancy wire mesh flexible hose that makes tire filling and pressure checking very convenient went bad and slowly leaked all the air out of the tire. The tire repair guy said he sees this problem often. I will now mix up a soapy water solution and squirt those hoses if pressure slowly leaks from the tires. Just a heads up if you ever find leaky tires, it might not be the tire.

Been there, done that. We had that trouble immediately when we took the coach home. I took the inside flexible filler hose off and everything has worked well since then.

Same here. We had a bad extension hose on one of the outside rear tires when first got the coach. Slow leaks like that are one of the reasons I just purchased a tire pressure monitoring system. Besides getting an alarm if the pressure decreases while going down the road, I can check the air pressure in all ten tires (coach and car) while sitting still, day or night, rain or shine, without going outside.

When we had a motor home, I finally took the extensions off the inside duallies. What I do on my dually truck is to carry a double head truckers air gauge and also a single flexible extension hose. At a truck stop, I can use their extended air chuck to fill the tires and if at a regular station, I screw on the extension hose and use it to fill a tire.

While in a campground in Fredericksburg, Texas, my right rear outside tire was loosing pressure. Since I'm kinda new to big rigs, I have managed to drag that tire through a lot of shoulders and assumed I had picked up a nail. Coach Net sent a service truck and a little soapy water showed the valve stem was leaking around the nut. The serviceman said he always checks the extensions first since that's the most likely problem.

Maybe I made a mistake, but I ordered my new coach with valve extensions. It just seemed such a nuisance to get on my back underneath the chassis just to check the dual internal tire pressure every time I travel.

Understanding that those who had trouble are more likely to post on the board, I hope that leaks are uncommon. But if not, can they be removed by me, or do I need to take them in to have it done?

I personally have used two sets, one set on my old coach and one set that came from the factory on the new coach. I had one leak on the old coach because the extension loosened up a little and no problems on the new coach.

On the old coach I checked the pressure every morning (caught the above problem by doing that which saved me a blowout), on the new coach I have a monitoring system so I can look at tire pressures every 6 seconds if I want to (the update rate of the TPMS).

That's my relatively positive experience, however I have also seen a lot of posts with negative experiences.
