Stock Dunlaps got me about 3k miles. The front was about 75% worn. Switched to pilot powers, so far they are a great tire.

 

I just bought a Metzler RoadTec Z6 rear for mine. I'd heard a lot about Pirelli Diablo Stradas, then found out that Metzler was made side by side with the Pirelli. Paid $151.00 out the door, mounted. I had heard of possible problems mixing, but I didn't have the $$ for the front too, and I took it right out on the road, and Ajax can't take the grin off my face!!! Way more confidence than the D220 I had on before. We'll see how the mileage goes, since I can't afford to replace in 2 or 3000 miles.
