Good tyres for 40S?

[Nick]

It handles really well now, with MSR5 shocks and Gorilla it's a dream, although it is abit on the heavy side, you can definatly feel that going around corners! :)

Hence why I need lite tyres for the Velocity wheels, trying to loose weight. I am thinking of the single conversion too but after that, I don't know how else I can make it more lite.
