S4 owners - anyone bother with winter tyres?

Hi Merlot

I always run snow tyres as I spend the winter in the alps. You're right, the recommended snow tyres for the S4 are 225/45 17. They really do make an enormous difference in mountain conditions, to the extent that in many countries in the event of an accident if one of the cars doesn't have winter tyres the driver is held partially to blame even if it wasn't his fault!

It is also almost impossible to fit chains to the standard S4 wheels but possible with the winter ones though in all the time I have used them they have been so good that chains have never been needed.

I would say that with quattro you would have to live somewhere very snowy in the UK to warrant the cost and hassle of changing them but the difference really is amazing if you have the need.

Hope this helps

Thanks Chris. I live in Scotland and have always been impressed with the S4 in any 'normal' winter conditions and snow up to about 6". After that I've got the Landie and its low ratio box.

In the middle of winter we still get 10-12c days but can go down to -5c at night. The only reason for asking is that the black ice recently has been terrible but I guess nothing grips in that.

Any thoughts on prices for winter tyres incl rims in the 225/45 17 size.

Does anyone think it would be worth lowering the preasure and if so by how much?? crazy.gif

If anything I'd increase the pressures on the S4 and did so last year. Lowering them albeit that the tyres are fairly rigid in their construction will increase contact surface area which on normal tyres would make them worse in terms of handling. Narrower contact patch with same weight increases weight on the contact patch and should help the car cut into the snow better.

However saying all that I'm not sure how much difference there would be increasing pressures by about 6-8 psi all round?

I'd say winter tyres are about as much use in the UK as slicks are in summer !

The 'old' S4 was more than capable when the snow fell last winter... all one week of it.

I had an A3 1.8TQ a few years back and took the missus skiing in the Alps... 1 meter of snow fell and everyone was told to stop half way up the mountains unless they had chains on... I just shouted QUATTRO out the window to the plod and they waved me through... fantastic time (was a pre-ESP car)
