Install a big enough inverter, use a Sears Craftsman REAL air compressor 115 Volt, carry an impact wrench..be done with it..You may have to get a big
enough truck...Its only money, after all...

pretty much all stores for professional air supply carry Puma
Amazon sells them
best prices usually on ebay

Many thanks Harald
You folks must think we don't have internet in Oregon ....(sometimes we don't !)
I searched for PUMA and their site does;t really direct you anywhere for sales....
BTW, are you related to an old line of Viking or English kings ? ,,the spelling of your name leads one to think maybe Danish ?

"big enough inverter"
Chuckie
"Install a big enough inverter, use a Sears Craftsman REAL air compressor 115 Volt, carry an impact wrench..be done with it..You may have to get a big
enough truck...Its only money, after all... "
The new Toyota Tacoma TRD off road models HAVE a big enough inverter standard....400 watts with motor running in the rear bed.
I have lots of small 110 compressors from my career in cabinet making....I don't want to carry the weight.
BTW, pro auto road racing teams just use lots of nitrogen cylinders for airing the tires but also for air tools in the pits and paddock on race
weekends....I was a transport driver and all around helper for a Grand Am team ...we always had 6-8 heavy tall cylinders...bazillion PSI.

you're not gonna run much of a compressor off a 400 watt inverter!

My 5 gallon porter cable compressor is rated at 10 amps at 120v, which would require a minimum of a 1200 watt inverter, but likely considering the
~85% efficiency of an inverter, would require at least 1600 watts with double that surge rating.
Such an inverter would require 2/0 cable or thicker over a short distance to the battery with proper thick walled ring terminal terminations and an
appropriate size fuse/circuit breaker to protect that cabling. Since MSW inverters cause electric motors to run much hotter, it would reduce
compressor motor life to some degree. PSW inverters, well increase the price by 3 to 4x.
This would place an ~ 100 amp load on the alternator, if the engine were running, which would quickly heat up an alternator to and perhaps beyond
220F, which is as hot as one ever wants to let their alternator get. At Idle speeds, even if the alternator can produce this much amperage, the
alternator fan is not spinning fast enough to dissipate the tremendous amount of heat generated.
A 130 amp alternator making 100 amps will heat up faster than the cold engine turning it.
If the engine is not turning, most healthy fully charged automotive batteries could run this inverter powering this 1200 watt load for only a minute
or two before the low voltage alarm started screeching and soon after the inverter would shut down.
At least 4 hours of driving would be required before this battery could be considered 100% fully charged again, and only if the vehicle's voltage
regulator allowed mid 14's to be held for that 4 hours, which is extremely unlikely.
Alternators are not the instant magical battery chargers that the general public believes of them.
There is always more than one way to skin a cat, but getting a huge inverter just to power a large carpenter's air compressor, just to fill tires,
makes No sense, especially when there are 12v compressors which can perform the task and take up 1/10 the space and cost 1/10 the price to accomplish
the same task for 1/6th the amp draw.
If one is travelling with a large RV, then perhaps carrying a large 120v compressor makes sense as one could just fire up the generator to run it, or
already have a large enough inverter and a large enough battery bank to power it for the time required.
I'll stick with my modified Mv-50.

sorry for the delay - I promised to give you numbers for airing up
pressure switch died right before the test.
hot wired the Puma compressor for the speed test
tires 295/75R16 (equivalent to a 33" tire)
tires on the ground carrying 7,000 lb (1,750lb ea)
Puma (3/4 HP) - 2 minutes from 10psi to 30psi
shop compressor (2.5 HP) - 2 minutes from 10 psi to 34 psi
will provide 10 psi to 35 and 40 psi a little later

So 10 psi per minute off the battery. Great!
To compare to the two small, cheap pumps I have
The MF-50 did 5 psi per minute
The Harbor Freight did 6 psi per minute
The cigarette plug Coleman pump did only 2 psi per minute
