Everybody needs to look at this very carefully

Mercedes blank out tyre pressures in manual and say refer to petrol flap.

Not in any of mine they don’t .

Besides the stickers , what does the vehicle handbook say re tyre pressures ?

Does it show the same or different pressures ?

 

[Pontoneer]

That’s not much use : all my manuals give this information , below is just the first one I went to .

What’s the point in quoting 40 year old data to the OP?

It is an example of what owners manuals always did , and still should , contain .

On my W124 , for example , part of the table in my filler flap is missing , although having had five estates and two saloons , I know the pressures , but otherwise I have the manuals to refer to .

A redacted photograph , on the other hand , is of absolutely no use to anyone , and a waste of space in the manual .

Wow, that's really shocking when you think about it.

Something else I would never think to check, just trust the wheels are doing their job especially if the tyres are staying up and causing no problem: could be a little too trusting maybe so perhaps I'll keep a closer eye on the tyre pressure from now on.

Crickey, only been on this forum 2 minutes and learning things already - good here in it?

This forum is a great place for people who do not have in their lives enough things to worry about......

I normally refer to the flap as well , but I do look in the handbook for other things , and if I had doubt about the flap , I’d check the handbook .

I used also to refer to the large , usually Michelin , guides that once were on every garage forecourt next to the airline .

They don't do that any more... probably too many wheels and tyres options per model these days.

Did you not check tyre pressure regularly before?

I check all 3 cars and my motorcycle weekly. It only takes a few minutes per vehicle.

Even less space on the flap , and if people , as many now do , go on to fit non standard wheels , it is all up in the air .

All of my manuals have contained lists of optional wheel and tyre sizes , but just the pressures for the standard wheels .

I typically check mine whenever I put petrol in . Any anomalies easily rectified when at the garage , but rarely needed .

The OP has stated that "38psi" is too low.

Based on what? PSI requirements are based on a number of factors including the mass of the vehicle and the tyre sidewall load index.

No need to check my Merc.....its tells me.....like any other car in the last 15 years or so. When I do check they never lose much more than a pound a month max....I think weekly checking is excessive personally.....if you are losing air every week something is wrong.

What's the correct pressure and where do you find it?

Something wrong with you?

these are standard wheels with the wrong recommended pressure

 

[DSM10000]

As said by others .

It depends on many factors. There is no "correct" setting. The manufacturers recommend a range based on load etc.

Do you know the load index of the tyres you have fitted? Are these the same as those supplied by the factory when new?

Something wrong with you?

Or with you?

Uncalled for!
