I know, it's been discussed before. But I have some questions about tire selection. Here's my riding:130 miles a week commuting, and some semi-easy to moderately difficult trails, with the occasional hard trail.(Desert riding, hard pack dry dirt and rocks) I want a tire that lasts longer than 3000 miles at least, but the more the better. I don't care about onroad comfort, my commute is short. I like the looks of the d606, but have read reports of one person getting 600 miles, and another getting 5000 miles. What's a realistic mileage count for a not spun out constantly or wheelied tire ridden 90 percent street (under 60mph) and 10 percent trails? Another question:is the "deathwing" really that horrible in the dirt? If a deathwing or other similarly more road oriented dual sport tire can get me through dry dirt okay and get twice the mileage on them, I might consider. I don't care about slippery and or wet situations such as mud or wet grass, just hard pack dry dirt and technical rocks. Generally, I'm under 30mph on a trail. Sand is semi important, I'de like to get through it, but I don't have to be going fast (first gear is good) Thanks for any input! btw-I currently have an almost toast rear pirelli m21 rallycross tire(bought bike used with tire pretty well worn), it's been great offroad, so that's where I'm starting from. I could handle a little less dirt perfromance for more mileage, but don't want to go too far into the street oriented realm.
