NSF tyre losing pressure

[sjw]

Are you always checking the tyre pressure when the tyres are cold?
If you tested them cold and then warm that could account for the pressure differences.

It's the car that's saying the pressure is low. If that's thrown off by temperature then it's a sh!t system

Had a set of 4 Goodyear F1 tyres a few weeks back. Second drive it threw up a low pressure warning while on the M5, fun times!. Found a lay-by and cheacked tyres, all were over due to the tyres being warm, double checked pressures when cold and told the car I’d set the pressures. Never came up again
