There are water traps that can be added to the outlet side of the compressor that will help considerably at a minimal cost.
I dont know whether moisture would be detrimental or not but it the quantity were enough it would sure would raise havoc with the balance of the tire.

Ron, whatever the humidity level of ambient air you are pumping into your tires is compressed at the same rate ( volume=7 to 1 I think) as the air pressure. I'm certainly no expert or engineer, but if you have a compressor with a storage tank, and you use it daily, it should be drained daily, you will be surprised at the amount of water condensed inside. A water filter/trap prevents most moisture from passing through to tools and tires.
Large industrial business's that use air pressure for power also have a refrigeration unit to chill the compressed air after it exits the compressor. This condenses remaining moisture so it drops out and is drained away.

Thanks Ray,

I'm sure the little compressor I mentioned above does not have any filter. I have noticed after toping of my tires, the nozzle has condensed moisture on the outside. I was just curious as to how much moisture gets inside the tire after several years of using the Truck Air Pump.

I'm with "az bound"

I have (unfortunately) become an expert on this issue. Two blowouts on the right rear inner dual qualify me as such-

.

I got the rig weighed on all the corners, as well as on the axles, and found out my right rear wheels are over weight with just fuel and fresh water in the tanks. The manufacturer has put the bedroom slide out, the 7000 watt generator, the two house batteries, the washer/dryer, and the gray water tank, all over this right rear axle leading to disaster in the tire arena.

The only thing that will save me from another blowout is maximum (COLD) tire inflation- I think. The Michelin charts allow me to go to 110psi and give me a slight cushion on this overweighted corner. And yes, I'll run the left side at this pressure also.

We'll see-

You may be able to shift to a higher load rating tire, or a larger tire size. Beware, however, of overloading the axle itself.

There are two posts in the " motorhome general discussion" forum that all should read. They were posted by an engeneer with 40 experiance in tires. I know it will be an eye-opener for many. At least I would hope so. Its under the thread " tire pressure links" It may just save someone some money, possibly even their life.
