Fitted and tested the K74 today. Off road it grips like a motocross tyre. lol. It moves around and bites like hell. Soft muddy is a breeze. Hard and slippy, just let it move around and it will soon find something to grip on,even in slippy river beds. Tarmac ?. Well what to do ideally is take it off road first, then once you get used to it moving around,take it on tarmac. ha ha . It feels like you have a rear puncture. lol. The blocks are deep and soft like an overdose of silica. I like it. Puts a smile on my face and I'm sure it'll settle down soon.
