I know this has been asking countless times before, but I have done a search and still cant find the sodding answer. I am off to Butlins in the morning (oh yeah) and really must check my tyre pressure before the long haul.

The problem is the car's side plate advises tyre pressure in BAR but all the pressure machines quote psi

Can someone let me know what PSI i need in my 335i e90.

Many thanks

As mine is only a 325d therefore I doubt the pressures are the same but 1 BAR is 14.5 PSi.

2.5 bar = 36 psi
2.6 bar = 38 psi

Hopes this helps.

Cheers mate, I cant imagine there being much difference

They all have bar on the scale too...

I haven't seen a PSI-only one for years?

Tell your garage they're breaking the weights and measures law only showing Imperial measurements on their air line

1 bar is 14.5 psi (it's like 14.5038 or something if you're on Eggheads, but I'm sure the tyre won't mind being rounded down ). All you need is Start/Run/calc and you're set.

[doughboy]

Calculator? WTF?

Just add 50% then times by 10, near enough....

i.e.

3 bar = 4.5 = 45psi

2.6bar = 3.9 = 39psi

Well you can multiply by 1.5 if you want to, sure, some people like to be precise is all. Thought I'd provide the necessary.

Ok, I can appreciate being precise, but it's not much use when the garage gauge is out by about 20% or more.

If you buy your own gauge it will have psi/bar/kPa anyway..

Cheers for the info, at long last I managed to get the simple answer I was looking for
