Gas Coaches and air compressors

I carry a Porter Cable Pancake, will do 150 lb.

I need 100-110psi and use the Viair. If I had to do over I'd install a set of Klein air horns and inflator combo.

It was fantastic. Filled the tires quickly and was very light, easy to carry and economical.

Works great in a diesel as well!

Light, fills my 275/70/22.5's to 110 on the fronts and 95 on the rears.

With 1 25 foot extension cord I can reach all six without plugging and unplugging the power.

Very small footprint in the storage bay.

We carry a 1 gal pancake compressor from Harbor Freight. Ok to top off. Valve stem leaked one time and had to put in 90lbs - took for ever but it got the job done.

I need 90psi for my tires.

Obtaining 90psi is the easy part. Finding space for a model with a decent size holding tank is another story, unless of course you don't mind the wait for airing them up. However topping them off on occasion, should work out pretty well for you.

I've been through a couple of Huskys from HoD. I don't recommend them. I have a Ridgid contractor grade compressor that fits in the basement, but it's too heavy and overkill for airing tires. It's on CL right now and I'll probably get a Porter Cable or that DeWalt.

I find that once in a while, a fill valve sticks open and completely drains the tire. Rather not take the chance driving to a gas station. I don't think the tire shop put the correct stems in with the Equal. I'm having extenders put on this month; hopefully it will fix the problem.

Porter 150 lbs from lowes. 100.00 on sale.

If you really need air compressor, read cut-in pressure as this is more critical than cut-out pressure.
If 120 psi compressor cuts-in at 85 psi, you will "never" get 90psi in the tires.

You actually can get 90 PSI+ with an 85 PSI cut-in. Just "bleed" the chuck a bit when the tank pressure drops below the current tire pressure to get the compressor to kick on, and then seal the chuck to the stem again as the pressure builds, repeating as necessary.

I have a Sears Craftsman...fits in a storage bin...big handle for easy moving. I THINK it's a 7 gallon tank. Goes up to 125 psi. I keep my tires at 80. Even so, with the smaller tank it can take quite a few re-charges to get the tire(s) up to 80 when needed. Works fine with shore or generator. Of course, I have to use a good extension cord and have 25 feet of air hose. With an in-line gauge. makes it easier.
