I put Kenda Small Block Eight tires on my mtb and they rock! I took them out in the park yesterday and rode over everything and they are so awesome. I like how they roll on pavement too. I went tubeless sans Stan's and so far they have held the psi well. It was my first *real* ride on the hiking trail and I'm ready to go again, except it's raining. If you want it to rain, just buy a bike or anything bike related. Hmpf!
