The Dunlop 407 rear, dual compound tire is the most durable, all around, best wearing tire I have ever used in nearly 50 years of riding. Usually 8-10 miles for a rear tire is about all you can expect. I got 25,000 miles out of my D407 before replacing it with 3/32" left on the tread. That said, I was looking at a tire book at a local indy and found it listed replacement 407s for $189.00. It was a brand that I never heard of before. I believe the replacement tires are just starting to hit the market after the required 24 months exclusivity that Harley shops enjoy. I went with the D407 at the Harley shop because I know what to expect from it.
