I would be worried about the size of the wiring to the cigar lighter socket.Could it overheat?

Not IME

I forgot to mention, that I've also had 2 footpumps in that time and both of those are deceased; cheap (Bourdon tube-type) pressure gauge failed, pump falling apart, hose end fitting came off, etc..

Both the 12V electric jobs and the 'traditional' foot pumps were cheaply made to appeal to undiscerning buyers. The cheap 12V pumps are more reliable than cheap footpumps.

[Dave Liquorice]

The socket should have it's own fuse in the fuse box, probably 10A, if that is inadequate to protect the wiring...

I ended up by chance with a flying dung (ie unbranded chinese) footpump. On ce it needed a drop or 2 of oil to restore pumping, but otherwise has been fine. I dont really see the point of electric ones, unless you have truck t yres or are physically unable to use a pump.

From an engineering point of view I like the 1950s style spark plug pumps. I expect they'd run on many modern electronically controlled cars.

There's also a crude method I've seen used for completely flat truck tyres. They put a teaspoon of petrol into the tyre, light it and its inflated ins tantly. This does not strike me as safe!

You can fit and forget.

I don't like the idea of filling tyres witha potentially explosive mixture. Anyway, I've got a diesel engine.

Like the post said. Try here?

Hairspray can be used to get the tyre to seal to the bead ISTR, you'd still need a pump and gauge if you wanted to get the pressure right.

Andrew May put finger to keyboard:

I also had the Michelin double barrel pump and I took it back almost immediately as not fit for purpose. Not only was the pump itself dire but the gauge veered wildly with each pump - I'd get readings like

20psi-35psi-24psi-22psi-45psi from consecutive pumps.

why would anyone fit a tyre pump?

Old carb cars deliver petrol/air, but I gather modern ones shut down the supply of fuel into a cylinder that doesnt work, so you'd get far too little petrol for it to be explosive. There's also no spark source inside a tyre. Diesel...

Well done, that certainly looks very like it.

[newshound]

That's very neat! I imagine you could do exactly the same thing with butane lighter fuel (have seen video of Russians in the arctic doing this on some sort of bloody great tractor).

[newshound]

Mine has (I think) a 20A fuse of its own. I use it with croc clips to the battery, not a problem as it has a 5 metre coily air hose as well.

Fit it onto the tyre valve - switchit and go and do something useful while the tyre is being inflated.

diesel doesn't have spark plugs.

[meow2222]

If you made tyre pumping a habit, I'd understand. To pump a tyre up once every 5 years I'd sooner have a handpump that'll keep on doing this than a short lived electrical gadget.

you dont say.

That's not how they work. The cylinder pressure drives a small oscillating piston pump that only pumps air.

I've had my electrical "gadget" for well over 10 years. It's pumped up bicycle tyres, car tyres, air beds and, what I believe is a called , a medicine ball. Oh, and a full sixe rubber doll for a theatrical production. Short lived - rubbish,

[meow2222]

Too often they are.

I've had my electric car tyre pump over ten years too, still works perfectly.
