Bought a new Specialized MTB which came with the Butcher Grid Trail tires. After only about 3 weeks the knobs started separating from the tire. Specialized dealer didn't think this was much of an issue, said "Yeah, they do that", lol.
Looked at some other reviews of this tire and decide to give it a go, no complaints here, almost two months in and the certainly have lasted better than the Butchers and hold the trail far better, very happy with the choice.;
