Hi,
Just purchased my first Mercedes its a 2009 E350CDi Coupe in white with Black roof, seems greta in the 20 miles that I have driven it. The tyre pressure warning light came on so I checked at first Petrol Station, 3 of the tyres were 48psi one was 24psi, the tyre size is 255/40/18 zr the 48 psi seems very high and 24 low, I looked on door check but no tyre pressure sticker, any advice greatly appreciated, do I have to rest the tyre warning once ar correct pressure. Thanks

Check inside the fuel filler cap. I would have expected mid 30s to 40 psi to be correct. The system will reset itself if you correct the pressures.

Thank you will look at this in the morning, looked at all sorts of charts but none had that tyre size.

My 2011 C207 350cdi albeit with 19s is 38psi all round, but think 18s will still be the same. Congrats on new motor, lovely car.
