Plenty of compressors out there that will pump to 100/150Psi. Big problem is the air volume required for larger higher pressure tyres, The compressor I have needs to pump the MH tyres to 90 psi. It will do the job but takes an age and gets very hot. It is a double Cylinder version and was bought from a TJM branch on special at $150.

It would be a much better prospect if it had a reservoir to be able to handle the bigger volume of air required but the you sacrifice compactness with a much bigger unit. Always a compromise.

From personal experience this really is serious air. http://www.seriousair.com.au/

The only problem with smaller 12V compressors is that they may be able to pump to a high pressure but their volumes (liters per minute) are very low.
This means they can take a while to pump up your tyres, but more importantly, if you have to do a flat repair and the tyre has popped its bead off the rim, you'll never get it back on the rim with a low volume compressor. You need lots of air and fast to do that.

If you are considering serious off road stuff where that repair situation may occur multiple times, get yourself one of these tidy little 230V AC units and make sure you have a large enough inverter to power it.

$199 from Supercheap.

Hi about this unit, can you tell us what you think when you check it out, I'm looking at doing the same thing, but didn't think about a 240v unit through the inverter, thanks Danny

I suggest that Stanley $199 unit is a bit on the underpowered side.
It is only 0.5HP.

That is smaller than the 12V Boss I am using which is 3/4HP.
I suggest you need t least 1HP and 1.5 would be better, and there will be no problem to run from the generator.

Cheers,
Peter

For most of us the time taken to pump up the tyre is not so important. This isn't a F1 race. Use the break to smell the air, put the billy on and have a cuppa, relaaaaaaax. 

I guess it depends on what you want from your compressor. There are lots of very suitable little compressors out there if you are just concerned with raising the pressure after having lowered them for dirt/sand etc.

To pop the bead back on to a tubeless rim, it is not the horse power of the compressor that is going to help you, it is the delivery of a large volume of air VERY quickly that is required. To do that you need a storage tank that can deliver that large volume in a couple of seconds.

I own one of the Stanley units and it only has a 5 liter tank, but if I wait approx two minutes for the compressor to auto shut off with the tank pressure dialed up to the maximum 115PSI, I can dump that entire tank in about 10 seconds and that fast flow of a large volume pops those beads on real simple.

Of course you could always just carry a couple of inner tubes.

Not into changing tyres on or off rims , just want a compressor to handle topping up 80 - 90 psi in a reasonable time . Found this one will have a look at it also, comments appreciated.

I have one of these style for top ups. It'll pump up a flat to 45psi in about a minute.

 .... but if I'm going offroad rock-hopping I take the Stanley as it is really easy to pop a tyre off the rim when you go slow speed bouncing over rocks.

Check out these BitDeals guys. Chinese imports. Great Solar supplier because they all come from China these days, but can't offer any comments on their compressors except they seem quite inexpensive like their solar panels are.
