I have them on my Toyota Land Cruiser 120. I choose the Alltereins because I sometimes like to use the car in offroad and very muddy conditions. The car is used 90%of the time on road. On dry tarmac the tires work good, good allroand grip, a bit of squeeking under heavy braking, but you would expect from a tire that is oriented more at offroad driving. On wet tarmac, the grip is very poor, especialy during cornering at a faster speed. Braking on wet tarmac is also quite poor, but acceptable.
On mud and stuff like that they are very good, and you can overcome about any terrain.
I didn't use them on snow or in cold weather since I have a winter set of tires.
If you keep in mind that, especially on wet roads, that the tires are not made to perform great on road, they are good, meaning that if you encounter a situation where you need off road capabilities, you can count on them. If you never use them off road, or your idea of off road is a patch of grass, you don't need them.
