not certain but probably under system/unitsDoes anyone know how to change the readout from bar to psi on the screen? It always flashes up low, but is OK when I check it, weird 🤔
That's why tyre pressures should be checked, and adjusted if necessary, regularly so that changes in ambient temperature are taken into account - at least as far as seasonal changes, no need to adjust them every day!thats exactly where it is.
if your tires are filled to 2.3 bar, the pressure will deop by about 0.2 on days when it is <5 degrees which generates a low tire pressure warning. once the wheels have been turning a bit, they heat up and pressure returns to 2.3.
The pressure still varies with ambient temperature just the same when filled with nitrogen.100%!
Tires are very important - with any luck, they are the ony thing that will ever make contact with the ground (other than my undertrays!)
Do people still get tires filled with nitrogen to over come this? Something I used to do on my M3, but not sure it actually worth the bother these days...
