Tyre pressure for my winters

PurpleTT · 12-03-2013, 03:24 PM

Anyone know what pressure I should tell the tyrefitters to put in my winters. They'll be put on the wheels before I get the car you see.

335d - 18" 415s with Conti TS830 Runflats. Square fwiw.

Spare chocolate éclair in the fridge for the first answer

gatsojon · 12-03-2013, 03:29 PM

Won't it say on the driver's B pillar?

Clearly I don't expect the eclair for that!

RichardM · 12-03-2013, 03:37 PM

It says it on mine, lists the winter tyres specifically.

An éclair is not enough to make me go outside in the cold to read it for you

PurpleTT · 12-04-2013, 06:20 AM

I haven't got a B-pillar or indeed the car it's attached to yet!

I hope I'll get the car next week, but tyres are going on this weekend. Hence the question.

Richard, please, pretty please can you have a look.

(the éclair appears to have been consumed, so it's an out of date yoghurt or half a cabbage, you choose!)

PurpleTT · 12-04-2013, 02:23 PM

Sorry but I'm gonna have to bump this thread to the top as I really do need to know.

Ok, I'll add last night's leftover chicken passanda if it helps

Can look once wife's back having stolen my car this evening. Apparently 'really like driving it as can upset male twats in their go-fast mobiles. It's hilarious in Sport + mode now you've changed the tyres'. Hmmmmm.... Perhaps I should never got her into getting racing licence and racing cars....

zooberoo · 12-04-2013, 02:35 PM

Does this help?

You sir, are a gentleman and a scholar. No hurry tonight, as long as I know before Saturday.

Thank you in advance.

Erm, yep I think so. Is it, er, 2.4 bar? the set on the right at the top? Blimey they made that complicated! None the wiser to be honest!

Me neither! And I'm getting my winters fitted tomorrow.

I think it's the M+S bit. These are not just any tyres... [insert joke here]

Ha ha didn't Nigella advertise M+S. Not going to see her on the ads for a while. (edit: although I imagine Coke will be on the blower to her pretty soon)

Well glad it's not just me who didn't understand that. What we need is a really clever forum member to decode this for us...

Tengocity · 12-04-2013, 03:01 PM

You said you had 18's, so it the the one on the top left of that pic, second line... you then have options depending on how loaded the car is

Unless she wants to give it another go with Charlie?

Sounds good to me. Triangle = front, circle = back. No marker = square setup. Boxes under tyres represent front or rear as appropriate. Load repesentated by Hansel and Gretels.

Does XL = runflat do you know?

GEP77 · 12-04-2013, 03:40 PM

XL means Xtra Load. M+S means Mud and Snow i.e. Winter tyres.

Bingo! that's the breakthrough I needed, thanks.

Oh and tengocity went straight to the solution, thanks.

Oh and the triangle = front etc. bit the Zooberoo explained, thanks

Got there in the end... so it's the second one down on the left for me:

[no triangle or circle as I'm square] 225/45 R18 95V M+S XL with 3 people = 2.8bar on the front and 3.0bar on the back.

Thanks fellas

steddyman · 12-05-2013, 02:36 AM

I know I am probably being thick here, but why would it not be the top one on the right?

That also appears to be a square 18" setup with winter tyres but with a lower speed rating. Not sure why different speed rated tyres would have a vastly different pressure.

Steddy man if you look at the top right spec box...this is an 18"setup with a lower load and speed rating tyre fitted.(91Y)

I'd have said the reason it's not the top right one for me is that whilst it is indeed 225/45 R18, it isn't an M+S tyre. The one below it is, but that's a 17".

By the way

2.8 bar is 40.61psi
3 bar is 43.51psi

Wow, wasn't expecting it to be that high!

-AndyH- · 12-05-2013, 11:46 AM

I think it's taking into account the pressures at lower temperature.

The correct pressures are 2.8-3.0 on the fronts and 3.0-3.5 on the rears - depending on the load.

I think mine are under inflated as they aren't that high. Will have to stop at the garage in the morning. Hopefully that is why the Pirelli ScottoZero's have been handling so crap.
