It won't if you choose to ride with MM and I!

If you want to get that kind of mileage out of a Shinko (or most other sport touring tires) - you need to ride on smooth concrete or asphalt and avoid Tar and Chip roads with sharp crushed stone aggregate, avoid riding in really hot temperatures, accelerate and brake slowly, and corner like you have a bowl of Goldfish on the seat.
