Do you use PSI or KPA for tyre pressures

i use Torr

Apologies, old timers disease well and truly to the fore today! How I got fuel confused with air pressure Buddha himself only knows!

sometimes i've used Pièze

PSI, except my non-LandRover tyre placards are in kpa.

PSI for me, but at work I use kpa.

I use PSI. Mainly because that's what I grew accustomed to inflating bike tyres (as a kid, it was the smallest number to read, and the servo inflator had that value in big red text on the dial [wink11] )

Bar makes sense though- 1 bar is approx 1 atmosphere at sea level, (14.5 psi in the old money). Or Add 2 zeros (x100) to make it kPa

So 30psi is near as damnit to 2 bar, or 200kPa

PSI all the way and just to throw in a red herring fish are always pounds and ounces.....not kilograms.

I don’t think they make imperial air anymore. They use metric air and then some people call it imperial, i.e. psi .
If you have a series Land Rover pre 1966 do you need to source imperial air for your tyres?

And don’t forget to get Winter or Summer Air...

Your tyre air pressure is totally reliant on the accuracy of the tyre gauge being used. One lazy afternoon on Fraser, two years ago, a few of us from different campsites were having a communal beer and the topic of tyre gauges arose.
We ended up with a total of 9 different gauges and they varied in readings by up to 8 psi. The closest agreement between two was 2 psi.

I use psi and Bar.
