Tire Sizes

[dArK5HaD0w]

when tyres r cold, i fill mine up to 38 psi.
when driving around, the tyres warm up to 41-42 psi.

For those switched from 235/40 R19 to 245/40 R19, what tyre pressures are you running? I have read some are still sticking with mid 30s PSI.

Im finding I have to up the tyre pressure 42 PSI all-round to stop the side wall movements and get some initial responses back.

The correct pressure is pump them up to what you think dead cold and they should rise 4lb when hot any more too hard, any less too soft
