What can I buy, preferably not over the £100 area, that would enable me to top-up/check my horsebox tyres at home? Even better if it can also be used on the roadside, though I do have breakdown cover.

I've seen things that connect to air-tanks, but I presume thats just for artics, not the brake airtanks under my horsebox!

I've also seen 12/24v compressors which claim to inflate to 160 PSI - do they work?

Any tips or suggestions wecome please :)
 
Hi. I have a lorry. I have a small machine. Size of a clutch bag. That hooks up to a spare car battery in my tack room. You put tyre pressure you want in. And hey presto. It does it for you
 
I just take mine to our local commercial tyre dealer and ask them very nicely if they’d mind checking the pressures and topping them up if needed. They are normally pretty good about it and I try to ring in advance to make sure I go at a quieter time
 
I've had a torrid time with burning out air compressors and learnt some lessons... its is around the £100 mark but Ring's RAC900 Heavy Duty Tyre Inflator takes some beating. It really is used extensivly by the breakdown companies for good reason. I'd say its worth buying well in this case :)

Just a note on buying anything cheaper - anything that can sustain compressing to the pressures a lorry needs cannot be run from the cigerette lighter plug, it needs too much power (amps) so will overload the circuit - its must run direct off you battery (run the engine at the same time) or from a spare battery as exracehorse does.
 
You should be able to get an air line to connect to the outlet on your air tanks. Might depend on the lorry. My 1993 Leyland DAF can do it.

I have a foot pump that is rated to do 100psi, but my legs aren't 🤣
 
Which chassis do you have/ What is the recommended tyre pressure for your tyres, which you can determine from the walls of the tyre. If it is a 7.5 ton it will need between 120 - 180 psi, in which case you need a proper industrial compressor as a home one will not go beyone 100 psi.

Not all 7.5 ton wagons have tyres that take that much. Mine are 92 and 98. If you don't have the owner's handbook, then check with your tyre supplier/lorry mechanic.

LF 45 160

Maintennce manual
215/75R17.5E
Single fittings 60.9 / 75.4 / 91.35 under max axle load - 91.35
Double fittings 71.05/ 78.3/ 87 under max axle load 98.6


So less than 100 psi.

I really agree about not buying a really cheap one. Mine burst into flames and it was only pumping up the tyres on the Volvo.
 
Lots of the ryobi one cordless inflators go to 150+

I can't post a link but the gun type one is around £40 and does 150. The next one or two up would probably be wise. You do also need to budget for a battery.
