Checking Tire Pressure

[ArtJoyce]

As BillJinOR mentioned. "180 Degree dual air chuck" also get the 180 tire gauge. Without these I could not check or fill any of my tires.

Also as other have mentioned, get you axle weight and use the tire mfg tire load to psi chart. ADD at least 10 PSI to account for one sided weighing more than the other. I add 15 psi to give us a little more margin so every cool day I don't have to add air. PS: The ideal weight should be taken when pack and ready to go. I don't do it when packed and ready to go. I Do it with our outfitted MH. I also have a full tank of fuel and Full tank of Freshwater and add 1,500 lbs for stuff we pack a the trip and add estimated passenger weight. I add this estimated weight with 2/3 of it added on the rear axle and 1/3 added on the front. I take the MH to a cat scale about 15 miles away.

Got out the air compressor, set to regulate 130 psi (Michelin spec on tire) to check by equalizing pressures between compressor and tire. Again could not position air hose nozzle. Good Grief … just want to be checking pressures regularly. Help !!!

Extensions will help. Amazon has a bunch of them with all manner of twists and contortions, depending on what you need. I bought a bunch for our last coach, found exactly what I needed, and sent back the ones I didn't need. For future checking, next time you're in a big truck stop, wander over toward the tools. There will be some really cool tire pressure gauges there that will be helpful. They might even have the extenders, come to think of it.

Unfortunately not, the ones on my coach were factory installed (I think) and
have been very good. I'm not sure of the lengths, but you should measure to be sure, and inner and outer wheels will not be the same, and where you mount them also will make a difference too.

I use a digital gauge with a "straight" locking chuck. A straight chuck will fit most stems. There are dozens available from Amazon.

If you are using an air compressor, many of the digital gauges allow you to connect the airline from the compressor to the gauge and fill and check as you go.

On my coach, because the valves just barely extend past the wheel, I have to use a 1" stainless steel valve extension, on four of my eight wheels, that I attach when I check the tires twice a year. I remove the TPMS cap, add the extension and check or add air if needed. Something like this.

If you really want to keep an eye on your tires, buy a TPMS product and check your tire in the AM before you drive off. You really increase the danger of tire failure by constantly messing/checking your tires unnecessarily. Tire air needs to be adjusted two maybe three times a year....max.

Hey friends,

We have a 2021 Newmar New Aire (Class A) and we tow a 2018 Subaru Forester w manual transmission. We have had a couple of blowouts on the toad tires, one of which caused a lot of damage. So we are thinking of getting a TPMS with a repeater for the 4 toad tires.

The New Aire has its own TPMS which gives pressure and temperature readings for all six tires, but they seem erratic and inconsistent. Occasionally, the inside tires on the duals show high temps and pressure even when properly inflated. Does anyone else have any experience with the Newmar TPMSs, good or bad? Are they accurate? Do I need to consider getting TPMS for all six tires on the rig? A TST TPMS for 10 tires would set me back $661. Do I really need it?

Thanks for your advice. Krikati
