Are 18" All-season Tires Available? If so, can they be run flat?

Also, does anyone know how SMG works? Is there a clutch? If not, is shifting by pressing the paddles only?

 

Not sure about the 18"s, but maybe this info will shed light on the SMG. I'm just not sure how current it is.

As far as I know, NO CLUTCH. Are the paddles even available in the US? I think it may just be shifting up and down on the shifter.

COOPS:

#1) I will reseach the tire question for you.

#2) The SMG that will be installed on the New 5 Series is the same system used on the Z4, not the M3 that the reply above this one directs you to. The systems are very different. I drove both of them at my local BMW dealer. Here is a link for the SMG used on the Z4:

And I would recommend that you read the great article LITSTER posted here:

Since the article is kind of long, I pulled out the SMG section and start a new thread. Here is the link

Thanks so much for this great info.
