I used this tire a few months ago, ran it for about two months. I ride everything from trails to street to concrete park. This tire uses a very hard compound, which allows it to dig into dirt nicely. However, this compound provides very little grip on street and park. With a Machete on both the front and the back, I literally could not drop in on a 5 foot tall, perfectly dry concrete quarter. The rear Machete always slipped out, and I ended up on my side. I found the front tire sliding like crazy when carving bowls or making fast turns while riding street.
This tire lowered my confidence while riding to very low levels. I ended up getting rid of the tires because I was frustrated with not wanting to even turn my damn bike because I was scared I was going to slide out.
I would not recommend these tires unless you ride literally nothing but dirt.
