Minimum requirements for an air compressor to inflate tires?

10kpharo · Feb 16, 2018

Hi, all. I have a '49 8N. I'm thinking about buying an air compressor (for a variety of tasks). What's the minimum requirement of a compressor to inflate those huge rears tires on my N? Thanks.

Minimum bicycle pump
Just will take a long time. Need less than
20 psi for rears,more for front. What else
do u want to do?

I have a $9 one from HF that would do it! How big a hurry are you in? Almost any air compressor made will inflate tractor tires, they are
generally low pressure. Buy what you need and can afford, if you are only occasionally going to air up a tire there are lots available for
<$100.

That is all I had and every spring every tire on the place needed air...!!!

Occasionally you can find a small diaphragm type compressor at an auction for $5.00 or less and they are built to last a lifetime..

Just stay AWAY from any "Oil-Less" compressor..they do NOT last..

There is no minimum because the smallest compressor made will air it up but it would take a lot of time. The more CFM the faster you can air it up. As for air pressure well that too is not all that much since 12-15 psi is all you need in the rear tires but the fronts you need around 30psi

I bought a handy 12V compressor from Northern Tool for less than $100 it'll air up a 28" tractor tire in about 5 minutes,have used it right much.Also have a compressor on a wagon
running gear with a 3-53 Detroit that'll air them up in a hurry(LOL)

The key to your question is (for a variety of tasks). You need to ask minimum PSI and CFM for whatever those other tasks are.

I used to use a bicycle pump for my JD A 38's. 300 strokes from flat to tight. Didn't take as long as you might think.

And I have an old oiless compressor that just keeps on going.

Have usued sparkplug one. That's all we had.

Rear tractor tires use low air pressure generally between 10 to 16 psi. The front tractor tires use more air pressure depending on how many plies, most newer tires have a maximum pressure on the sidewall. It does not take much of an air compressor to inflate one. A bicycle tire pump will work if you have enough time. Any air compressor that works for your car tires will be adequate for tractor tires too.

Depends on how patient you are. Any compressor can do that but to generate that much volume it would take a long time to fill up a tire with a too small of a compressor. Since you say "multiple tasks" I think I would get one that was at least 5 cfm at 100 psi. This would enable you to use a home sand blaster or spray paint.

If I were buying again, I would buy a belt drive model for shop use, not the "buzzer" types which eventually cause hateful
thoughts to roll around in your mind. Belt driven are more expensive and less to choose from but that's the way I would go
for shop use. For the house, etc, a little lightweight buzzer type is pretty handy.

Donald Lehman · Feb 16, 2018

If you are just using it for blowing up tires on cars, trucks, and tractors, 5 cfm will work alright. If you are going to use about any kind of air tool you need about 10 cfm as a minimum. We have a couple of the little portable oil less buzz boxes. They are handy to move around and do the job if you are not in any hurry. But they are next to worthless for running any air tool.

The pressure is the requirement. if you want 30 lbs you will have to buy a compressor that produces over that. size of tank will dictate time it takes TO FILL your tire. Bigger the tank is more volume so it will fill faster. higher pressure will fill it faster. CFM will matter only when you use tools, sand blaster, etc as they have a requirement of cfm to operate them correctly.

Well if you watch late night tv, you know you need the Air Hawk! It takes outside air and compresses it and injects it into your tire! Amazing! No more cans of messy air to deal with LOL!

Once upon a time before my shop was up to snuff I had a Leyland with big fat tires on the back and one went flat a ways out from the shop.
I spent quite some time running back and forth with my little 1 gallon compressor.
Not too much later I invested in a much larger compressor and revamped a dead 11 gallon compressor to make a portable tank.
