Portable Air compressor for 22.5 inch tires?

What does everyone use. Those 12 volt units will take forever to inflate I'm sure, I have never used one on a big tire. since they overheat easy and are slow it would probably take a few hours I am thinking.
Since my new MH will have the 22.5 inch tires and no spare I will carry a plug kit and need something that will pump enough air to fill it in a reasonable time.
Has anyone spotted any under 100 bucks that will do the job?

I had an AC powered 2 hp 8 gallon unit (that was too big to be 'portable') that said it would air up to 115 psi. It would not come close...sold it. My new MH has on board air, so I don't need one any more. I don't know if you can find one that will go that high and be 'portable.'

This one does the job easily and takes up very little space.

Sears: Online department store featuring appliances, tools, fitness equipment and more

You can buy it online or at your local Sears store. Just get a truck chuck for your rear duals and you will be good to go.

The advantage vs using onboard air is speed. This compressor will top off your tires very quickly.

I use the ViAir 200PSI compressor and 2.5 gallon tank. It's main function is for the air horns, but I have also used it to air the tires and inflate mattresses etc. Mine is this one : ViAIR 380c Compressor 2 gallon System 200 PSI PN: 20007 but you can also get them to remote mount the tank and compressor depending on the room you have.

I own the Sears model mentioned above. It does a good job. It's very portable and has a max. inflation rate up to 150psi. The Harbor Freight unit looks a bit bulkier and has a max up to 115psi. Of those two, I'd go with the Sears model.

I use the Poweser Tank compressed Co2. Best money I eer spent. Small, super fast, no noise. Easy to refill, I only need to top it off once a year.

I use the 3 gallon Husky compressor below that I picked up at Home Depot to take care of the tires on the truck and RV. The load range J 17.5" Michelins on the RV require up to 120 PSIG. It's small enough to fit in the toolbox in the bed of my truck.

I just bought a Campbell Hasufeld 120 volt, 1.5 gal tank, 115psi, $99, Ace Hardware. Small foorprint, stores easily in my 5r, weights about half of the Sears compressor. I lowered one of my tires from 80 to 70 just to see how long it would take to fill the tire. About 5 minutes. Works for me.

If you get the Sears unit, look in the manual for the break-in procedure and follow the instructions.

Basically it is a 15 minute process under no load and then you are good to go.

Been there and did not do that. We went FT in '06 and that was one thing that I thought that we needed. We have been on the road 4+ years without and have had no problems. Turns out that we only need air about once a year and it is easy to find a place or borrow someone's. Yep, all them folks that replied have one and most would gladly let you borrow theres. Just remember them at Happy Hour. When fully loaded (the Bounder) it calls for 95 front and 90 rear, we run 100 all around which gives us 5 lbs of 'fudge' room. Sidewalls on our 22.5 XRV's is 110 max.

I can inflate my 22.5 tires to about 107 PSI using the on board engine compressor connector.

Since I need 115 PSI in my front tires, I also have the Sears 6 gallon 150 psi compressor that I bought used from Craig's list.

I just received a Harbor Freight email catalog that showed a similar 150 psi unit for sale for about $120.

I do not carry the compressor on the rig, but I could if desired.

Are you looking for a "top off" compressor, or one thats intended to really work?

I had great luck with this porter cable 150LB unit.
Its "just portable enough" and just powerful enough to run air tools with authority and fill tires with a modicum of speed.

Porter Cable C3151 is the minimum workable unit for me. and Ive tried a lot of portables out in the dessert.

Porter Cable Electric Powered Air Compressors | ToolBarn.com

Anything Under 135 LB just wont cut it for me for my pickup truck and toyhauler - much less my motorhome. You sit there at the nozzle forever.

I tow through the sand and have to "air down and air up" each time I hit the sand and I spend a decent amount of time going from 18lb to 55lb for 8 tires, even with this unit and I cant imagine anything smaller not taking forever.

It will NOT run off a honda 2K.
