What width winter tyres can you run?

[Hark]

On standard Z4M wheels.

Read several threads but really not sure if should be running 255 on the rear or narrower as they're winters.

225/40 18 all round, but you could run 255s if you wanted

i know tyres are being done to death at the moment , but do you not have to bother with a staggered set up then ?

[Wondermike]

No, not if you don't want to.

[ballington31]

cool thanks mike

So 225/40/18 all round is ok? Even on the wider rear rims?

How wide are the z4m rims?

Guess it works out alot cheaper.

Have a read of these few posts here to see what Darren has done on his ///M

I run Blizzak LM-60's on a staggered setup using 225/45-18 front and 255/40-18 rear. I rarely drive in the snow but I run winter tires for better safer handling with winter temps and wet roads. Yes a 225 tire can be fitted in most cases to a 9 inch rear ///M rim. Tire mfg make the recommendations as to the size rims a specific tires can be fitted to. The 225 Blizzak's I use can be fitted to a 7.5 to a 9 inch rim.

If you can run 225, why do you run 255?

Since I avoid driving in the snow my tire dealer suggested staying with the 255 rear tire. There was very little difference in price so I went with his suggestion. Last year was the first year that I ran the staggered setup and it worked fine even in snow compared to 6 previous winters on 225/45=17's.

Bill I have 4 new M3 replica wheels 18x8 can I fit 225/40/18 up front and 255/40/18 at the rear or would you recommend all four corners to be 225/40/18

Thanks in advance.

Rolf-Dieter, you get a lot more snow than I do and I know that the narrow tire is better in the snow so I would likely go with 225's all around.
