I've been running them since they have dropped. honestly, one of the main reasons i got them was cause they were made out of some sort very squeaky rubber compound to make them Squeak! I was running some machete tires before and they squeak over any terrain. But i just wanted to know if anyone feels the same. It's kind of a dissapointment that they really don't squeak at all for me. Maybe its a special terrain where they do squeak, idk. But overall i must admit they're really great tires, could take a nice beating and long lasting super grippy where you wont slip and eat it.
