What are people putting their 18inch winter tyres pressure at ?

Im thinking 35psi (cold) is this ok or to much?

My 18" winters are 225/45/18

I'm running what the door sticker says, (2.2) 31 front and (2.4) 34 back

My fronts are that size and I am the same as you - think its the lowest pressure recommended on the door sticker.

My 225/45 18''s are 32 front and 35 rear (cold) Took this straight off the plate inside the door and it feels right.

I have 225/45 18’s winters on at the moment and had them set to 2.2 front and 2.6 rear, however had a car full of people and gear for a weekend away recently so put up to 2.4 front and 2.8 rear. Although I’m in the car most of the time on my own I have just left them higher for now. They are well within tolerance.

That’s E90/91 profile tyres. F30/31 should be 225/45R18

Is there an issue with this tyre size or just speedo errors?

Thanks people,

It most likely is 225/45/18 as I was just going by what I thought it was
