Not too bad
September 23, 2009
I rode the tire front and rear on a variety of terrain. The tire is a great freeride tire. Running higher pressure, it was extremely fast rolling through freeride type dirt jumps. The tire tracks pretty well through rough and loose turns we have here in Colorado. The sipping in the side knobs help the tire hook up in corners and hold the line. I did not feel the tire fold or roll off the knobs. I do run higher pressure typically to prevent tires from rolling off the rim in hard cornering applications. I did not have the tire roll on me once. The tire loves hard pack and hard pack with loose over top. Knob penetration was excellent. Tire size was accurate. Compared to a Maxxis 2.35 and 2.5, the WTB was pretty close to the 2.5 Maxxis even on the same rim. Maxxis tires are notoriously narrow for size, so it was refreshing to ride a tire that was on par with what the claimed size was. Braking performance was consistent and predictable. The threshold for the tire breaking loose was also predictable and consistent.
My one complaint with the tire was the casing. It is a bit on the thin side for a DH tire. I think the tire would be a great all mountain tire where speeds are lower and trails less rough. Each of my 4 flats resulted from a square edged hit and a pinch flat even with 45 PSI in the tires. All of the flats were rear. When slowing down as result of the flat, the tire would roll off the rim and due to the 4 flats, the tire would no longer hold the rim properly and tears in the sidewall resulted. The tire was thrown out. I am continuing to run the front tire and it is holding up very well.
The rubber durometer has been great, slow enough to hold, but wears extremely well.

broke two leavers as well putting them on a mavic 729 rim but once on it road well over rocky dry ground (fernie) as a rear, would want something with larger knobs as a front tire.
it wearing fast after about 20-30 runs the middle row of knobs is well worn (running at about 35+ pounds) but for the 15 bucks on chain love i cant complain you could put new one one every other week for the hill season for the same price as a minion...
Good tire while it lasts

Came stock on my bike and are ok on everything from hardpack to mud but are always a bit drift anxious they seemed. Main compliant is that although the rubber is nice and soft it doesn't last more than a solid week of riding everyday. Mostly DH and freeride style riding. Find some on sale and you cant go wrong.
P.S. they are really hard to mount. Get a nice tire lever or two for sure

This tire is pretty good an any freeride/dh type of riding. It hooks up well and rolls pretty easily.
Some people mentioned it is tough to mount. I found the trick to easier mounting this guy is to make sure the bead of the side you are mounting is in the center of the rim (not in on the lock in outside portion where it will later pop in with pressure). As long as you keep all parts of the bead off the locking portion of the rim the tire will have enough slack to fit. I've done this plenty of times without any tools and it's really not too bad as long as you follow that.
Not easy to mount

I killed 2 tire levers and 2 tubes trying to mount the 2.1 to my DT Swiss rims. WTF? Was kind of excited to run these on the front and see how they did vs. the Nevegal I had on, but I'm not sure I want to sacrifice another tube for nothing.
