C63 w204 estate 19” 245 265 tyre pressures warm/cold

[Theador]

I’ve gone one profile up on the tyres 245 35 and 265 30 r19” on the C63 w204 estate. Should I keep the pressures the same 41/42psi and is that a warm or cold reading

I run the same tyre sizes using the standard pressures and it's measured cold.

Tyre pressures on the fiuel filler flap and in the manual are a guide only and you should adjust based upon wear.

The guidance doesn’t change with such a small change to tyre size, so go with the guidance and adjust based upon wear:

Always measure tyre pressures cold.
