Tire pressure question specifically for 18s w/ all-season tires
On the fuel door, there is a M+S section at the bottom.
Since my car came with all-season (grand touring) runflat tires, which have that M+S symbol, I’m under the impression that the F/R pressures listed there are the ones I’m supposed to be using.
The reason I’m checking is because there is also that section for 18” wheels at the top, and I have 18s. But my thoughts are that the top figure is for 18s with max performance summer tires.
So I’ve been running 36/35 (F/R) since delivery. Correct move?

Weird, I have the 18 c43 coupe with runflat all season 18 in.and my door shows 41/39 psi (frt/rear) as suggested pressure as ONLY recommended pressure. Which I have been using.

And when you say door, do you mean fuel door, or the inside of the driver's side door?
