Tires are the achilles heel for the R III's if you ride somewhat aggressively. For the Tourer you have lots of choices. My thoughts on the matter come after 43700 miles on regular rockets. I will not go to another set of stock Metz's. Most folk like em, not me. With the weight and torque it produces, finding a tire that can handle the machine is an ongoing challenge. When you find some that work please free that info here. Going dark, not recommeded by me, is just one way to thwart the economic hardship.
