I just upgraded from 25" Terracross tires to 26" Terracross XD tires on my 2007 Grizzly. The Terracross XD has an extra sidewall ply and a more durable rubber compound than the old Terracross tires did. I really liked the old Terracross tires on my Grizzly, and put 1300 miles worth of rock riding on them with no punctures, and still almost new looking tread depth. I liked the 25" Terracross tires so well on the Grizzly that I took them off the Grizzly and put them on my Rhino. That left me with needing another set of tires for the Grizzly, so this time I chose the 26" Terracross XD tires.
There are some notable differences between the old and the new Terracross tires. The 25" Terracross tires had a more square profile with a flat tread surface. The 26" Terracross XD tires have a more rounded profile. The 26" Terracross XD tires seem to have improved build quality, because they ride much smoother, and do not have the subtle shimmy at high speed on pavement that the old Terracross tires had. Its nice to see that ITP has improved in that area, and the new tires are as smooth as silk. Traction also seems to be better with the new Terracross XD tires, which is especially noticable at corner turn in. The old tires did have a slight tendancy to push in turns if you entered the turn too hot. The new tires bite and turn instantly, and there is enough improvement that it actually took a few minutes to get used to it. Turning is incredibly precise with the new Terracross XDs, and they still powerslide extremely well, which was always a good feature of the old Terracross. Its too soon to say how durable they will be, but considering that I never had a problem with the old Terracross tires, the new Terracross XD should be every bit as good, or better. After one days ride I'm very happy with the new tires, and would highly recommend them for trail conditions experienced in the western USA. The new 26" Terracross XDs seem to work better and ride better than the old style 25" Terracross tires did.
Here's a picture of the old flatter profile 25" Terracross tires.
And here's the new rounder profile 26" Terracross XD
