I run a new Echo tyre at about 15/16psi on the back. Dont have a problem with punctures. My monty tyre on the front is around 10psi. Feels nicer in my opinion.
Bloxx on smooth rims are terrible dude. I'm still running ZOO's. Deng just always changes his mind on what to do whether its right or not but it is Dang none the less.
