Tyre pressure guages

[mjt]

Which would you trust?

I've been using the manual gauge for as long as I can remember.
However, I was given the digital one the other day and it reads about 2psi below the manual one.

That seems to match the info at the petrol station I use, but always assumed the petrol station one to be incorrect.

What you do you think, OCUK?

I'd probably trust the digital one, given it backs up what a third reading says (the petrol station).

for me the digital ones seem to be pretty rock solid in their reliability, had a cracked wheel a short while ago and was loosing pressure at about ~2.5 PSI / hour which I thought seemed bogus as hell, went to local petrol station to check and it turned out it was bang on, haven't doubted them ever since.

Manual - old is best
Well at least I would trust not the petrol station nor the one that looks like it cost 20p in China, but who knows.

Neither of them, if you wan't accuracy get one of these!

£170 for a tyre pressure gauge? Must be joking!

the problem with the manual gauge is over time it will wear, and come out of the sleeve easier, and therefore further out to read higher

This one is £1.24 quite often at Tesco fuel stations, keep an eye out for it!
