air compressor max
Just a quick question for you pros before I go to the store and ask the same question.
I want to buy an air compressor which has one air tank and states the maximum pressure to be 100 psi. Will this compressor put 100 lbs in my tires or do I need to get a stronger one.

I may be wrong but I don't think it will. My max pressure is 150 and about 110 is all it will put in the tires.

compressor operation works on differential. If you need 100 in the tires, a 100psi compressor will do it, but the last several psi will be verrry slow. A 125psi compressor will do 100 reasonably.
Next spec you will want to watch is the volume, usually stated at 40psi & 90. you'll get less volume near 100 than is stated at 90, but higher is better for keeping the fill time reasonable. Usually when you get into the >100 range, the tires are fairly large volume, so a compressor w/some lung capacity is appreciated.

You will be very disappointed if you don't get at least a 150 psi compressor.

A great little compressor is the Porter Cable 6 Gallon. It handles everything I need to do, including an air gun to remove tires if I should every need to. It weighs about 35 lbs and can be found at Home Depot or Lowes. It's worth the look.

You need at least 20 PSI more in the air compressor than you need in the tire.. And still more is better
A 100 PSI compressor, in theory might blow a tire up to 100 PSI, but it would take a long long time to do it.
A 150 PSI compressor (Sears or Harbor Freight should have them) will do the job in a more reasonable amount of time.
NOTE: you know where it says 100PSI max on the tire.. READ IT AGAIN, that is not what it says, READ the ENTIRE sentence
Maximum load xxxxxxx pounds at yyy PSI
Now find out what the PROPER pressure is for that tire

You must take into account the cut-in or low pressure set point. If you need 100 psi in your tires but the compressor does not re-start until it's pressure switch reaches 80 psi, you have a problem. Assuming you buy a compressor with a high limit of 150 psi, and a low limit of 80 psi, this means you must bleed-off pressure until the compressor re-starts and once again reaches 100 psi before you may resume filling a tire.
My solution was to buy a Search results for: '150 psi compressor'
It is not nearly as fast as larger compressors but it serves me well for adjusting air pressure on the road.

Yes, You will get to 100 psi just before He!! freezes over.
If you want to be able to top off your tires to 100psi,(if you really need to) then you will need something a little more robust. Try the 150psi 1.5 gal Sears Craftsman Air Compressor #00915309000. I think you will find that acceptable at $89.99 on sale. I beleave the weight was stated as 25 lbs.
You may find more info on this subject if you do a search on this same site for "air compressors".

On board air?
Is your chassis gas or diesel?
I ask because some diesel if equiped with air brakes and air ride have a service port in one of the storage bins.
It will be mounted very high, above the hatch behind the edge, requires one to get on their hands and knees to see.
Ours is in the bin next to the main door, handy when one is too lazy to get the long hose.
The down side is you have to have the engine running, and the headroom is only about 20 or so PSI, but there is no cut in/cut out problems.
Upside is only a hose is needed.
If you have air on board and no fitting then one could be added as long as it is installed in the correct place, must be in the aux circuit, same one that feeds the springs and throttle.
If not then it was a shot.
