My motorcycle definitely gets a fair share of straight highway miles either to get to the twisties or to visit friends across state lines. My most-recent Metzeler tires were the wonderful ME Z4 which were excellent. Predictable, durable, communicative, and confidence-inspiring in wet conditions. Out of the last five sets of tires, three of them have been Metzelers.
I was forced to switch to Dunlops when I picked-up some large screws in my tires hundreds of miles from home and had failure. Had a local shop install the only D208s they had in stock. They're OK at best...but can't hold a candle to the Metzelers. They almost seem hard and loud compared to the supple Metzeler rubber.
Once these Dunlops have been worn enough, I will swap back over to the Metzeler Sportec M-1 tires front and rear. I'm willing to sacrifice dry performance for a bit of "insurance" in case I get caught in the rain. These probably won't get the same mileage as the ME Z4 model, but will probably get significantly more than the Rennsport, ME Z3 Racing, or the Sportec M3.
