When I have to replace my tires, I will probably not go with CST, however, they seem to be doing fairly well so far.
They grip well in the rain, which is a big thing for me. I'm not sure what problems are having with these tires, but there is a lot of negative talk about them.
With that said, I have always thought that the general ride of the Super 8 is a bit harsh, which I mainly attribute to the suspension and hard seat.
I added foam to the seat and that helped quite a bit.
The good thing about the hard suspension is that the scoot tracks well on smooth roads.
