I got a Jobmate hand truck from Mitre 10. It works well, but the tyres are flat. I'm not sure if I can take it to a petrol station and inflate the tyres with their pump or if I need a bicycle pump. Pics below.

Anyone know? I googled it but couldn't find a way to tell the two apart. I know they're slightly different as you can't pump up bike tyres at the petrol station without an adapter.

Thanks! I'll take it over to the service station :)

It's a Schrader (lower pressure) valve which is the same on all my bicycles, my hand trucks/trolleys and my automobiles. No additional adapter is normally needed unless you have a Presta valve (high-pressure on racing bikes) or a Dunlop valve (the old ones we used last century).

Thanks - it's been a while but I found some things I pump up with a hand pump (which I don't have any more) don't work with a service station pump. Maybe things have changed, or I haven't recalled correctly.

Hi, that valve will most certainly work with a car pump at the garage, however if due to deflation, it has regressed into the rim then you may have trouble getting enough of the valve into the pump dispensing wand, you may need to pull it out of the hole somewhat. Also its possible that the tyre is flat is that there is a significant hole in the tube, and its letting air out as fast as you can get it in.

That's a TR13 rubber valve which is the most common valve, all threads are the same (universal) so any pump will do.

Pliers to pull on the stem just to get enough bite for the clip-on chuck on the pump should suffice, either that or a cheap plastic valve extension from BNT will sort it out.

If the tube is punctured then I would recommend replacing with a bent metal valve, that valve hole on the rim looks like it needs a clean too.

All done, worked fine at the service station. Yes it was very flat, I had to push my thumb against the base of the valve from the other side of the tyre so I could get enough pressure to inflate it. Next time I won't let them get quite so low before I pump them up!

Some garage air pumps squirt air in then adjust down to setting. Small capacity tubes can be popped.

Use a lower PSI with these, otherwise you could find the tire pops off the bead.

Also, if you can not get a service station connection into the wheel you have to use the old school hand pump (with flexible connector). It’s a pain - they should install valves that have a bend so they are easy to get to.

24psi at the service station worked fine thanks Doghouse. The tyres were marked 25psi max.
