Quick one - A539s

[F&B]

Are these Yokos directional?

Thanks

No, they're asymmetric...doesn't matter which way they run, but they have an outside edge.

Excellent - out of interest Markcup, what pressures do you run road/track?

 

[MarkCup]

No idea.

If I'm not using all of the tread width...I drop some out.

If I'm rolling too far onto the shoulders...I put more in.

Depends on ambient temperature, track temperature, pace of sessions etc.
