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?
I would assume you are correct in your assumption. Makes more sense to run M+S or snow tires as 18 inchers making the tire size irrelevant, thus more importantly, based on material.
thank you for this picture! someone rear ended my 2016 c450 AMG, the body shop replaced the fuel cover/door without this sticker. i going to take a picture of this for reference.
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.

Thanks for the reply!

You're welcome! This photo is actually from another user on the board, I just re-posted it for context.

Well, I have the sedan, so that likely explains the difference. Fairly different setups between the sedan and coupe.
And when you say door, do you mean fuel door, or the inside of the driver's side door?
