They have a square outside edge that allows them to dig alot better than round edge.

2nd time buy. 100km. very strong.snow, sand very good. wet surface honest.

Almost at 70k miles and still plenty of tread,

I have less than 10k miles on the tires, they are in need of being replaced now.

The best , no noise and a good drive in the sand

Very nice riding tires. Very quiet.

best tire I've ever owned and i basically drive for a living

Ko2 tires didn't make it a year before the tread is 60-70% gone on all four of them

Rides way smoother and quieter than I expected. Much improvement over the stock Firestone's.

These tires a month ago and I love them in the snow
