Inflating low tires

[Ajax MD]

Yes, I searched the archives. Lots of CTIS information and info about mounting tires but not exactly what I'm looking for.

Simple enough question-

On a NON-CTIS vehicle, with a tire that has already been mounted with the split lock ring and inflated to full pressure but has slowly lost pressure over time, down to 25 psi, is it safe to simply inflate the tire to its normal on-road operating pressure? Do I need to remove the tire and chain it or cage it? Does it matter if it's a dually or one of the single steering tires?

My truck has sat for several years and a few of the tires just need a topping up. None of them are flat or have any real leaks as far as I can tell.

Thanks.

You will be fine just airing them up.

I think if they did not go flat and sit you should be fine.

Right. None of the tires have gone totally flat and deformed.

The lowest I found, was 25 psi, so "off roading" pressure. I think it took 8 years of sitting for it to drift that low. Oh- these are ordinary NDT's.
I imagine that driving the truck with tires at all different pressures would cause a rough ride and would also be hazardous, so I want to get them all up to pressure. Some of them are at the proper pressure.

As long as the bead is still in place then its safe to add air. If the bead has moved away from the lock ring at any location from being flat then you have a risk.

If your worried, get a clip on air chuck. Then you don't have to stand right there and hold it. I have a 50' hose with a clip on air chuck on one end and a regular with shut off valve on the other. I can set the desired pressure, clip on and go do something else without worry. Very useful when filling the big 16.00s too.

Oh, I'm using a clip on chuck. Think about it though- if a tire mounted on the vehicle blew a ring off, it could rocket across my yard, into neighbor's yards, possibly. Fortunately, it sounds like the ring is usually still firmly attached unless the tire goes totally flat.

The M&R guys in my unit always did the organizational maintenance on our trucks so I never got to see the fix-it side of things. I performed a "hard card" (safety checklist) before I drove a vehicle but that was it, hence my ignorance.
