I’m glad we’re all agreed that z-maxes were shite. I’ll add to that the Maxxis Rendez.. Moderately fast rolling, but went round corners about as well as a curling stone.
Worst tyre for me today is my godforsaken Bontrager mud-x’s. They’re nice, grippy, pregressive, light weight tyres, but they seem to have sidewalls made from moth wings!
