Just acquired a horsebox based on a 3.5 panel van. This will live by the stables with no mains. So I am looking for a pump to take the 225-65 R16's up to 70 psi.
Amazon have a "Vertex" for £50 which seems to have a decent spec:
Make sure the power lead is long enough to reach from the tow vehicle to the compressor when it's being used to inflate a tyre on the trailer.
Mine wasn't. :o(
Fair point, but that's an "easy" fix. I was really looking for advice on whether this sort of product is man enough for commercial tyres. The feedback is OK but this is such a well informed group!
Oh, indeed. Although not in the dark and pissing rain on the hard shoulder of the M42.
Quite so.
I have a "Draper" one which will inflate trailer tyres but takes a *long* time. I suspect it wouldn't be man enough for a large commercial tyre.
I don't know about that particular one, but most 12v compressors seem to say that they work up to about 200 psi. The most annoying thing I have found is that they tend to not have a switch, so you have to either unplug it from the socket, or install an inline switch in the cable.
If you've got a flat tyre in that circumstance, either
A - It's become punctured on the journey, in which case your compressor won't be any use.
B. - It was already well deflated/flat when you set off, in which case it serves you right, you should have done your checks before setting off.
C - You've got a puncture and you've just discovered the spare is flat. See B.

except that you may have a can of sealant, but not with enough pressure to achieve the correct running level.
Or, as happened to me in the 1970's driving round the Brussels ring road into Germany, an HGV flung a metal plate under my offside wheels, puncturing the front and giving me a slow puncture in the rear. But after changing the front I was able to complete the next 150 miles by stopping every 25 miles or so to top up the rear with a footpump.
It was fairly exciting slowing from 80 mph and crossing three busy lanes to get to the hard shoulder on a high embankment. While everyone used to say "don't brake if you have a puncture" I ended up braking from 50 once I was on the hard shoulder.
And the pressure gauge dials are usually wildly inaccurate.
No argument. I always use a separate, better-quality one, that I know is pretty accurate.
I had one once where the indicated pressure was at least twice the real pressure!
My current one starts at 20 psi. I don't know idea how accurate it is, I always use my own gauge, but it appears to be way off.
I find the mechanical 'pen' style ones are generally more accurate than the 'digital' (button cell operated) ones.
