The manufacturers recommended winter tyre is the Continental contiWinterContact, though that would not be my preferred choice as it’s D rating for fuel and wet grip and TBH a full winter tyre in the UK is overkill, you’re better off with the ContiAllSeasonContact

We have a slight incline off the estate and even with the slightest snow its almost impossible to get up the bank. Generally look out of the widow and if there is white stuff it stays in the garage.

Did get one tip which has worked in the past from a neighbour who had a 3 series. He found that switching off all the traction control and aids meant that although the card did skid, second gear and gentle on the throttle worked to get you moving forward.

Could be wrong, but I seem to remember reading something in the manual about turning off traction control in snow until moving.

I do tend to drink a lot of beer though, so may be bullshit.

I'm pretty sure I've read that somewhere as well.

I think I also read that in snow you're better off without ABS too, although that isn't switchable! Something to do with a locked wheel building up a wedge of snow that helps stop the car I think.

But I may be wrong too if I had been on the Shiraz.

Once again thanks all

Fit Michelin cross climate 2 tyres if you live in cold and wet area of the UK, full winters if you see a lot of snow. but watch this video also:

The only all seasons I found in required size for rear (275/35/19) are Vredstein Quatrac and they don't even have good reviews. So I gave up on initial idea of buying all seasons and bought winter tyres from Ebay. Rears were more difficult to find, but got pair coming from Z4 and just bought fronts and will collect them next week. Car is arriving in 2 weeks and I plan to stick winter tyres on it straight away, to go to Europe for couple of weeks. I hate tyres swapping every season, especially since you can't use Z4 to haul tyres to the garage for a swap, so it will be extra hassle. That's why I wanted all seasons.

I used SLK in real winter conditions and without winter tyres it was useless in minimal amount of snow, so I expect something similar from Z4.

That’s the main issue with keeping your existing alloys and swapping/storing tyres.

My friend stores winter tyres with BMW Milton K., he said it's only £25 per year, so maybe Croydon one offers something similar. This way, I could minimise trips with tyres to the garage. Have to check with them.

I put winter tyres on today. I was pleasantly surprised, that 3 tyres fitted into the car, so only had to carry one separately. Went on a quick drive, to make sure all is ok. Car didn't recognise tyres, so had to choose manualy and "Other" size. 19 inch wheels were not listed under winter/all seasons.

I think that winter tyres are quieter than OEM summer ones.

which winter tyres did you go for?

[Roadster_Surrey]

Vredstein Wintrac Pro.

[sars]

You’re a bit keen on swapping, we’ve not had a frost yet

[Roadster_Surrey]

I'm going to Europe on weekend, don't know for how long. It already snowed in the Alps. I watch web cams on Stevio. And in past, I encountered snow twice on higher mountain passes in Switzerland, on August Bank Holiday.

[F1SpaceMonkey]

why is it impossible to find cross climate tyres for the M40i front and rear? silly question but do the rears have to be 275/35R19? or could i fit 255/35R19 tyres to the rear? Are the rear alloy wheels larger than the fronts? I really wanted Michelin Cross Climate 2.

[Roadster_Surrey]

That's a good question about size of alloys and whether they are different. Brochure doesn't mention exact size. I would expect the rear alloys to be a bit wider.

On previous car with identical wheels (AWD), I put 285/30/21 winter tyres to replace 275/35/21, simply because I couldn't find decently priced original size. There was -3% error in speed measurement. There are websites where you can compare sizes and error in speed display.

On Mercedes which has staggered wheels, I put winter tyres narrower by 10, both on front and rear. And I used this car in Germany, so it experienced actual winter.
