RS6 Snow Tire Questions for Gary
The OEM tires are 255/40-18, and have an XL load rating, with service description of 99. (The RS6 is a heavy car.) The TireRack website lists an alternate 18" size, 225/45-18.
Here are my questions:
Does the alternate size have the same rolling diameter?
Would you personally choose the alternate for snows for better winter performance? (I know it wouldn't look as good.)
Choosing the alternate size expands my choices from just the Blizzak LM-25 to include the Dunlop M3. It seems that reviewers are more enthusiastic about the Dunlop. However, both tires in the alternate size have a service description of 95V, less than the stock 99. (The LM-25 is 99V in the OEM size.) Would the alternate size be a safe alternative for such a heavy car?
Do you have any personal preference for the Dunlop versus the Blizzak given my winter driving conditions?
Also, should any of the 18" tires fit on any 18" wheel I buy? (Or do I have to worry about the width of the wheel.)
Thanks.
Given that the tires in these sizes are high performance snow tires, I'd personally go to the more narrow size for better snow traction.
95 load rating works fine on this application.
Both have been very good tires. We've had a bit better experience in snow capablity with the LM25, which feedback in dry grip has been a bit better with the M3.
As long as the wheel that you choose is between 7" and 8.5" these will work well.<ul><li><a href="http://www.tirerack.com/a.jsp?a=AR8&url=/winter/index.jsp">winter</a></li></ul>
