I didn't know you could get a tyre like that K180.
This is it? Interesting, very much like the US style flattrack tyres... I understood those don't really work on our surfaces?
They tend to keep our local track (Canberra) pretty wet, would that tyre work?
I've been using Motoz X-Circuit which I really like, it seems to hold up well and is especially good when it's dryish or blue groove:
How about the Dunlop MX71?
Someone recommended the Kenda Triple Sticky, I've never heard of that either:
