Jerry M/D, I have commented on this thread earlier. However, I just got back froma 3500 mile vacation with passenger and a fair amont of luggage.All different types of road surfaces. My original front tire (D407F) was cupped so bad at 11,251 miles it got replaced at BigSky Hd in Great falls Montana. When I left my rear looked like I was going to make it to 15,000 miles easily, but when I returned and had a front fork seal replaced dealer said I only had 3/32 left. On the bright side I ordered a new American Elite 180/65B16 from Sporttour (866-761-0936) delivered to my door for $185.90 I think their website is sporttour.com I checked with Dunlop before I ordered this tire and they said it is compatable with the D408 that I just had installed on the front. I hope I get at least 15K out of this American Elite. Dunlop told me it would be quieter then the 407 and it sure looks like it has a lot of tread. I hope this info helps someone out. CAHDBIKER
