We have a 2000 A6 2.7T and are looking for snow tires. We have looked at the Tirerack Website and they only recommend M3 and do not list the M2. Can the M2 be used and what are the differences?

Thanks!

Very few differences between the two, slight tread pattern change... just an update rather than a whole new tire. They're so similar that you'll often see me refering to them together. There are very few survey results in yet, so the numbers will be misleading on the survey results page.<ul><li><a href="http://www.tirerack.com/a.jsp?a=AR8&amp;url=/winter/index.jsp">winter tires</a></li></ul>
