I just wanted everyone who hasn't tried these tires to know, I tried the D952's on my XR650R. The front tire is AWESOME!! In the Colorado rocky mountains, the front 952 sticks like glue to sand, rocks, and mud, and holds up to paved roads well. The 952 rear tire is a different story. 1st off, the sidewall is so hard, I had a fight just getting it mounted. 2nd, as I was mounting it, I noticed "Sumitomo Rubber Company" printed really small on the side of the tire. Sumitomo is a Japanese tire company. I have worked with Sumitomo truck tires before, and they are known for having very stiff sidewalls. Before I saw the 952, I didn't know Sumitomo had any to do with Good Year (Good Year owns Dunlop). I suspect, Dunlop designed the tire & tread for the 952 rear, but then contracted Sumitomo to make the tire, (probibly why it's an "economy" tire). Trust me, this tire has no grip when compaired to any other Dunlop, and it got burnt up in less than 500 miles on my XR650. Since that rear tire, I went back to running a rear D606 with the front 952. The 606 sacrifices a little off-road grip, but lasts over twice as long as any non-highway tire. I think I may stick with this combonation for awhile.
