W246 - Are they original tyres?

[51315]

Just bought a 2020 B Class AMG Premium+ with 14k miles, one owner, and wonder if there is a way of telling if the Pirelli Cinturato P7's were the originals - approx 6mm tread left all around (225/45 R18).
Also, if it's a clue, petrol flap pressures say 38psi front and 34psi rear. Does that sound right? Many thanks.

The tyre wall date may give a clue , four numbers in a box eg 3620 means 36th week in 2020

As per above, tyre date code is a 4 digit number - week and year



Yes to tyre pressures in the fuel flap being correct

Original tyres will probably have MO after the size to indicate they are Mercedes Original fitment - though they could have specified MO replacements....

14k and 6mm, assuming they were 7/8mm new sounds about right.

Thanks for those replies ... and do you reckon tyre pressure is right - at petrol flap pressures of 38psi front and 34psi rear?

I tend to do 33 regardless which works for me comfort and wear wise . But everyone has their own potions

Yes, go with the flap figures. You can go up or down a psi or two but in general stick with those
