Those tires are loads of fun. They are pretty heavy but kevlar reinforced. I think the tread is designed to start talking to you in turns, because it does that. I can lean the bike way over and those little grooves in the side tread start squeaking. They offer tremendous grip and at 2.35" offer a nice cushy ride as well. I fear no potholes or curbs, I actually look for curbs to jump. The bike really feels like a huge BMX bike.
