Tire pressures, extenders and airing up etc

So today I went through the pain of checking tire pressures and airing up to the correct pressures. I say 'pain' because doing the inner rears was a PITA!

The coach is just over a month old and came from the factory with rubber extensions:


The extensions put the valve only just through the outer wheel:



Checking the pressure wasn't too much of a hassle but actually putting air in was horrible! In the end, the only way I could do it was reaching between the wheels to hold the extension while using the other hand to push the air chuck onto the stem. This involved lying on the floor and generally being a contortionist!

On to my question. I have read a lot on here about extensions, TPMS systems etc. I have pretty much decided that I will buy a TPMS but don't want to put it on the rubber extensions - I think it will cause these to flap around and probably work loose or cause some other problem.

So I'm looking at replacing the rubber extensions with solid metal ones, and then TPMS on to the extensions. Recommendations on what extensions to use would be appreciated, and also how to anchor everything to the wheel. Will the weight of the TPMS sensors cause excessive load on the extensions and ultimately cause a failure / leak etc?

As always advise and thoughts appreciated.

Thanks
Dave

These are the guys to go to for quality dually valves. Dually valve kits for Motor-homes, Busses and 6-wheeled chassis. Too bad the factory didn't offer the upgrade. You'll have to have the wheels pulled but they are solid and trouble-free.

I have those same rubber donuts but with about a 6in. Metal extender. Works very well, even with the tpms sensors on them. You're on the right track.

Thanks for the input.

I've ordered 6" metal schrader valve extenders and a TST 507 TPMS. Probably won't get it in time to install before our next trip (4 day trip to Lake Ouchita this next weekend) but should be able to get it installed the following weekend.

At least, after today I know my tire pressures are good, and next time hopefully it will be a lot easier

Thanks
Dave

I would recommend braided valve extensions, this will bring both valve stems out so you have easier access to them. You can then add TPMS to them. If you have any questions regarding TPMS please let me know.
Thanks,
Mike
