I picked up another set of the pirelli's. They dont stick like I want them to in the hills. I usually run bt-016's but cant seem to get crap for milage out of them. The diablos handle really well when riding two up in the hills and I've managed to get 5200 out of my last rear tire with them. I typically only get 2,000 to 2,300 out of the 016's. This is going to be my 6th set of tires in the last 2 years. I also have another set of 016's waiting for the warmer months. I figure I'll burn up this rear and then slap another set of diablos on the bike for the second half of the winter riding season. Should be able to manage to put on around 8 to 10K miles during the cooler months. Gotta love warm southern california riding weather.
