You could run a 255/45/18, that would be close to OEM diameter (about 1% off) and these SO-4 Pole positions get nice reviews for a Max Performance Summer
Bridgestone Potenza S-04 Pole Position
Ranked just ahead of the DW, but both are the same price FWIW.

 

I bought 255s to make the speedo error only 5% optimistic. Haven't checked to see what they did to the odometer accuracy.

 

What tire sidewall series and wheel diameter are you running on the 255s?

 

255/45-18 on the Sport Sedan duckfeet. Speedometer error dropped from 7.5% optimistic to 5% as measured by GPS app.
