Carl,
I don't think that I'll ever go back to another tyre quickly. They are absolutely awesome on- and offroad. Excellent handling on wet and dry tar, gravel roads, sand and lastly MUD!! Bit of road noise (not much) but luckily the frontier's got a good sound system

They have a directional tread pattern though which makes it a bit of a pain in the backside when it comes to the spare tyre, but I have solved that problem by using the Kumho All-terrain tyre as a spare.
