Air Compressers
 

I got an old arb compressor in my jeep, It is a small unit, really best for my locker, but not so for filling big tires. I gkts 33x 12.5 tires, and to air up from 12 to 30 psi takes near 5 minutes per tire.

It is like this one..

My jeep buddy has this higher capacity newer compressor......

his compressor can fill my tire in 2.5 minutes.

So I want a higher volume compressor. what are good options? The arb unit is very pricey, top,of the line. Are there less expensive economy units you know of that offer good reliability?
Parting with near $300 for this compressor is tough.

Viair makes good products; have used them for work. I'm not sure if you're looking for something mounted, or something portable, but something like this runs under $100 on Summit...

If you dont use your AC you can actually convert your AC compressor to an Air Compressor. They make very strong air compressors for tires and such.
