Apologies, mods, if this is too off-topic but it is related!

I just had to get 4 new tyres for my car and bought at Costco (1 week before their £20 off when you buy 4 deal but that's another story Rolling Eyes

)

Anyway - they have a big sign saying their tyres are filled with nitrogen and I now have green valve caps Cool

I didn't think to ask at the time but if/when I need to top up, can I just add air as usual? I assume I can as air is mostly N anyway, but I'm sure you clever folk can advise.

I have never checked my own tyre pressures as the main tyre suppliers,Kwik fit & National for sure, give free safety checks,both tread depth & pressures. Just pull in and ask.

My father bought me a high quality push on tyre pressure guage for christmas some years ago. It's calibrated with a laser from Mars, runs on kryptonite and is built by someone in a brown nylon coat with a beard.....you get the picture. What it has taught me is to never trust the readout at many airline points. They're supposed to be regularly calibrated but having once inflated then drove home on tyres Fred Flintstone's would be proud of, I checked them and was horrified that I'd put in enough for me to float should I encounter a flood. I don't trust them much these days. Good little gizmo. Bless me Dad!

THEPOET

Hi,

Nobody has mentioned Tesco's yet. My local Tesco garage has an air machine that goes past 70psi. It has a digital readout. Have seen the same type of machines at other Tesco stores.

asda in sutton thinks that theres wont go past 30 - i know i asked

i think they are wrong but with such a low estimate i wasn't taking the risk

is 20p/40p classed as a risk? I'm giving up self employment based on this principle.
