I got 12K out of my stock Dunlops before I switched over to Avon Venoms. There was still ~2K left on the tires, but they were too hard IMHO and I definitely like the Avon's as they stick and stick good!!

 

8k on the rear 16k onthe front 03 Ultra

 

Just replaced my rear a few weeks ago. 2,500 miles and a nail later I'm doing it again. Damn, why always a nail in the new tire.

On stock dunlop 401s I got about 15K. Then I tried the Dunlop 491 MU(140)90-16 and got over 20K on the back. Fronts always get over 20K.

 

I was told by a young tech that the amount of weight on the bike can cause more or less wear. I ride two up 1/2 the time don't think I will get 12000 out of my rear.
