I put one of these on a lease car after taking out the sidewall of a two week old Michelin, after 7k miles the Michelin Primacy was dead and the Powertrac still had 4mm+ of even tread left. The car went back at the end of the lease with the Powertrac (4mm) and the Michelin was replaced for the MOT!
My driving style is 'drive it like you stole it', I don't tend to hang around and my wife drives like the police are chasing her. Don't get me wrong, these aren't high performance tyres and they were fitted a 4x4 that only needs to cope with wet grass, a bit of mud, snow/ice and the pair of us kicking it around the country lanes. The handle just as well if not better than the Michelin's.
I plan to fit 4 of these to our other car as soon as the others wear out.
