Some interesting info that could pertain to this: Kyle recently showed me a chart that shows that the actual tread width of the Potenza S-04 275/35 tire is a full inch narrower than that of the Michelin PSS of the same size. So its a half inch closer to the fenders/liners in the rear and just slightly less in the front.

If you do the math the tire contact patch of the 275/35 S-04 is the same size as the tire contact patch of a theoretical 250/35 Michelin PSS.

We should do a bit of tire swapping next time we are at the airfield, I'd be real interested in feeling the different grip levels.
