I currently have over 9000 miles on my OEM Dunlop tires. I ride both dirt and pavement. These tires will for sure reach around 10,000 miles before I will change them. I agree that these tires are not great dirt tires, but no 90/10 tire is a great dirt tire. And yes, all 90/10 tires will slide out from under you on the wet grass. I am old (The over 70 something crowd), short, ugly, and fat weighing over 300lbs. I have been riding both dirt and pavement sense 1958. Never had a time that I quit riding, or ever been without a bike. These 90/10 Dunlop tires are not the greatest, but they are not that bad either.
Yes, I have already purchased my next set of tires. The new tires are 50/50 tires. I ride about 75% street and 25% dirt. I have to have another biker on the ride when riding way off road, as I can no longer pick up my bike. Lots of nice folks usually come running to help when I drop my bike when on the road or at filling stations. All most all my drops are when stopped. I travelled over 100,000 miles on my previous bike in the last 3 years. I had both my knees replaced sense July, so I only have 9000 miles on my AT that I have had since November. I have not been able to shift gears, so how good it is to have a DCT. However, the knees are now doing a lot better. So now I can once again stand on the pegs and RIDE!
