Rear tire after 1,000 Km
Front tire after 1,000 Kms - almost no wear
The rear has some visible wear, but very little. At this rate I expect to see at least 6,000 Kms from it, and more for the front tire. So far, I'm quite impressed at how they're holding up. Last summer when I bought this bike, the previous owner had just installed a brand new original equipment Trailwing on the rear --- I had that thing worn out in about a month, with about 1,500 Kms, and traction sucked. These Twinduros handle quite well on the street for a knobby, although they don't stop nearly as quickly as the Avon Distanzias when a cement truck suddenly makes a left turn right front of you. I've locked up the rear tire several times, and rather easily I might add. The Avons had great stopping grip when you grab the brakes really hard in a panic stop.
While I've only done a few short offroad Kilometres with these tires, I am very impressed with their grip. I found a trail along some hydro lines and it quickly turned swampy. I was able to plow through like a bulldozer. If these tires last as I expect they will, then I'll surely buy them again. I also hit a Kilometre or two on a dry packed dirt & gravel road and they gripped as well as any offroad tire.
