My point was that you guys in England are all moaning that your BMWs are worse than useless in the snow but refuse to believe that changing to winter tyres will transform the car in tomething usable. Where as the BMWs in Germany with winter tyres on handle snow and ice without a problem.

I've just pinged an email to Yokohama - I'm finding the "premium" Winter tyres I bought off them total cr4p.
Wife just had a serious brown trouser moment (she's a good driver and knows the 335d as well as anyone could) when the car fishtailed badly with no provocation on the slightest of bends. I've found them pretty dreadful too.
It might be my expectations are wrong - I expected more noise, faster wear but otherwise good tyres. What we've got is tyres made of polished teflon that have turned a powerful but well sorted car into a bloody dangerous machine. The traction light is on almost constantly - on Summers you need to really take the pi55 to turn it on.
Since getting them I've read (typically!) a fair bit about poor performance in warmer conditions but we can't change them every time it rises above seven degrees.
Maybe if you live in Scotland or up North but not for "it hardly ever snows" Cornwall. They were in case we needed to go to meetings in London but I think we'll use the 4WD van or borrow a Defender 90 on proper Winter rubber. My Defender 110 on M&S tyres was brilliant in snow and ice and fine in warm conditions too.
I will put them up on ebay (I suspect Yokohama won't reply) but that's going to be a lot of hassle and wasted money. BU99ER. Still, at least we didn't buy 17s to fit them for the M135i...

How many miles have you done on them? I have the same rubber on my 330 and i had a few moments with them. They seem to have settled down now (or i'm driving around them) after 1k miles use.
It's strange that they are crap on damp roads at 7-10c but seem to have good bite on frosty roads.

I noticed on some cars that the specs for tyre pressure reccomend higher pressures for winter tyres. Presumably because the sidewall are a bit more floppy I guess.
Usually only by about 3 to 5 psi, so I doubt it would make much difference if they are that bad.
Maybe also worh checking the date stamp (first twio digits are the week and last two the year) of manufacture. If I had new tyres that are a couple of years old I'd not be too please...shelf life is supposed to be 5yrs MAXIMUM!! (understanably people use them for longer than this, but their performance DOES degrade)

Right been looking into getting some of these but what speed and weight rating IS required, I currently have 225/45 R17 97V extra load but the tires I'm looking to buy are 225/45 R17 91H will these be ok and what difference will it make?

97 = 730kg
V = up to 149mph
the tyres you are looking at are
91 = 615kg
H = up to 130mph
Ideally you need to see what tyres are the manufacturer's recommended specification and make sure you don't go below those. So if the manufacturer states 97V then a 99Z would be OK, but a 91H probably wouldn't.
Of course with winter tyres there maybe some leeway, but I don't know that for sure.
It's the load rating that will cause you issues as the speed rating is less important as long as you don't exceed the limit of the tyre's rating although your insurance company may have something to say about it too.

The 97V part of the tyres you currently have refers to the load rating and the speed rating. 97 = 730kg V = up to 149mph the tyres you are looking at are 91 = 615kg H = up to 130mph Ideally you need to see what tyres are the manufacturer's recommended specification and make sure you don't go below those.

So I have a V9 Widetrack STi on the standard multispoke wheels so does anyone know the standard spec of the tires or can tell me where to find the information?

Tyre pressures raised slightly, two pressure gauges used an averaged to ensure precision.
Just driven it and tried to provoke it - one slightly odd fishtail (easily corrected) and a fair bit of TCS light action but nothing too bad. It could be that BMWs are just VERY sensitive to pressures.

Whilst technically correct, in actuality I'd be inclined to disagree: The speed rating can have a impact on how a car handles.
I learnt that the hard way a long time ago when I had a pair of new tyres on front of my XR3. Both tyres same brand, model, size and load rating, but somehow one ended up being H rated and the other was V rated (other than that the tyres looked identical).
The result was the car would wildly veer off to the right under hard acceleration, and generally unstable under hard braking. It took a while to figure out the problem as originally I thought my diff had seized - it really was that bad.
Of course having the same load index and speed rating on the same axle ensure no real stability/safety problem, but from what I've experienced the structure of the H rated tyre is different to that of a V rated to the point that it does affect handling. Maybe this could be part of the issue Brun and Matteyboy are suffering

Wurzel might be worth tapping for some info regarding Mattee and Brun as he lives in Germany and is bound to know people with winters on their BMWs.
On my old Volvo (which is hardly a direct comnparison I grant you) I have not experienced any issues with the winters on dry/wet roads, but I hardly cane the old V40 around the place so maybe that has something to do with it although I don't drive it Miss Daisy either.

Well I spoke to Yokohama and they are going to take the tyres back and inspect them. I don't think there's actually anything "wrong" with them (apart from them being useless) so I'm sure I will still have the hassle of Ebaying them but at least it eliminates any doubt.
If they could do a partial refund I'd be happy - I cannot be ar5ed to try ad sell them on! They certainly won't be going anywhere near the M135i once it arrives.

I've now done circa 3k miles on mine and having played round with the pressures (now 42r + 39f) i think i have found a setup that works.
They did feel terrible on greasy roads and very "floaty" at speed but i guess that being non rft they had way more movement in the sidewall. Anyways, now that i'm running the increased pressures, the car feels very much like it did on the run flats.
I still observe caution on damp roads but am happy with their performance on frosty mornings where they seem to have goo bite into the surface. Bring on the snow - that's why i bought them
