Yup, there's a mileage hit. I have S-02s on 17-inch Aero wheels that I use interchangably with my 16-inch MXV4-shod SE wheels. Without calculating in the S-02's smaller diameter, I take a more than 10% mileage hit using them. If I added the odometer error it might even be 15%.
The MXV4s are low-rolling resistance tires (says "Energy Series" or something like that on the sidewalls), and the Pole Positions are not (sticky compound, stiff narrow sidewalls, etc.). Plus, in my case they're wider, which means there's an aerodynamic drag hit too. Even though it's a PITA, I switch to the stock wheels for long trips because of the better mileage and because I don't see any need to wear out performance tires on the boring interstate. I think the MXV4s will wear out sometime in the next century.
