I agree, this is very subject to riding style, road condition and specific tire choice. The most I experienced on my Valkyrie was 15k. I did not select car tires that are designed to go 80k. Always more interested in a softer tire designed for better traction. To compare, the most I got from a motorcycle tire was 11k on the front. I've always been amazed at reports of people who get 20k plus on their front tire.
this is a picture of my Michellen Alpine Primicy with just over 20 Thousand miles on it.. I ran one before and it had ovr 28K when i took it off and it may have had 5 k left when i removed it...i plan to ride this tire to Brice Canyon in May and back and before next fall to put on a new one...Dave44
That is a hard question to answer. Most likely the answer will be somewhat different for each individual. It mostly boils down to riding stile. Which means how often and how hard you roll that throttle.
A good rule to follow regarding a rear tire ... generally you will get 25% more miles from a CT than a MT. And even that can very depending on the throttle. For example, the increased traction of a CT can inspire confidence which may transfer to increased throttle which then decreases mileage.
I have no information about double darkside. On the front, I'm using either an Avon Cobra or a Bridgestone G709. Currently I have an Avon mounted.
Hope this helps.
The picture in Monk's signature is what Monk means about increasing confidence in corners while throttle is twisted...if you all look closely there's sparks flying

my miles are only this good because i do most of my riding on slab. Riding here in Florida is more than kind to tires, they really are not under any stress here. Also at home i don't have any twisty roads...so it is expected that tires last a long time..And when i do hit some curves i usually don't push it very hard, usually go a season with out the sound of chrome on pavement *smile* We all have a different style and very different conditions. Makes no matter as long as we are on 2 or 3 wheels and enjoy the ride...Dave44
