Glock in your sock
Ouch, I have a near new set in the shed and they are fragile with the same knobbage issues.One week old Continental X-King MTB Tyre - ProTection
My old Verticals lasted forever on the back and only lose a few knobs but also get skittery once they get a worn and blunt.
Trouble with tyres is that there are so damn many on the market and you just end up collecting them by accident.
