Tire inflation

I carry 12V compressors, but TV and TT tires only lose about 1 lb a month. I visually check them at every stop but haven't needed the 12V's.

I air them up at home as needed with my 120V compressor.

Many people do carry a small compressor with them.

For filling/topping off tires, a large air tank is unnecessary and can be an annoyance (as you need to wait for it to get up to pressure).

I have a Fini AirBoss, which is fairly reasonably priced and quite compact. It has a turn-off pressure of 135 pounds (and a turn-on pressure of 110 I think), so it would work for your tires, but not be ideal. I've been impressed with it so far; it's relatively quiet as small compressors go, and seems pretty well built. (I do wish to point out that "relatively quiet" is not at all the same thing as "quiet.")

For 12V powered compressors, Vair seems to have a very good reputation. On the other hand, the cheap little inflators that are available most everywhere are nearly useless for large, high-pressure tires.

For the 8 years we were full time I carried this compressor in the basement storage bay of our 5th wheel here and it never failed. To top off the 110 psi you will need a 150 psi compressor to make your life easier. This unit was easy to carry and store, at least for my storage area, your space may be limited and then you will have to find a smaller unit.

I have a small Husky unit, about $35. Plugs into my trucks electrical system. You may need a bigger unit for that much PSI. Good thing to have at any cost.

Hi Barry,

We do travel with a compressor, but my tires only need 80PSI. I think you should consider a 150PSI compressor with tire pressures like that. Otherwise you could be there a long time waiting for the compressor to cycle on and off enough times to fill your tire. If you had a 120 PSI compressor, you wouldn't have much difference between your tank and tire pressure and it would take forever to top the tire off, if the tank even got low enough to kick the compressor on. With a lower pressure compressor you could be stuck in the pressure range of where the compressor kicks off and turns back on which would be a pain. Also consider what you need to power it, either a strong enough inverter or a generator.
