They now have a "New" S12 XC. Anyone tried them yet? My bike had the original S12's on it when I got it...Front looked almost new, back was about 50%. Front is still on my bike, but I switched to the Maxxis Desert IT on the rear. I liked the performance of the S12 better, but not enough to make up for the wear that the Desert IT gets.....and it's not that the Desert IT is "bad", just not as good in the soft wet stuff..... Looking to see if the new XC version really does what they say as for wear... From their web site: Every aspect of MICHELIN® XC-series has been designed to maximize traction. Now a new rear rubber mixture improves durability by at least 25% compared with previous versions. Redesigned casing construction helps improve traction, feedback and feel, and speeds warm-up time. The new S12 XC™ tire is highly versatile and excels in a variety of terrain. Reformulated rubber mixture improves durability by at least 25%, compared with previous MICHELIN® tires Improved grip compared with previous MICHELIN® tires, thanks to new rear tread compound and changes in casing design Redesigned tire structure incorporates an additional casing ply under the tread, which helps improve flexibility of the tread area. This in turn improves feedback, traction and warm-up time. Thicker sidewalls in the bead area help increase lateral rigidity, further improving feedback and performance. Proven, championship-winning tread designs remain unchanged from original M12™ tires Aggressive shoulder knob design promotes cornering stability Soft- to intermediate-condition tire for motocross or offroad Tall, narrow knobs for mud penetration Front knobs turned 45° for mud evacuation.
