Jorrie, I must say that the Kumho's I have on are fantastic..... but ... I can only compare them to the Bridgestone Duellers AT (31") I had on before. there is no contest which is for me the better tyre. As I said before they are quite noisy on the tar, and re-balancing them seemed to be difficult after they had done a few Km. In the wet, on tar they do stick like sheeeet to a blanket.....

.... ( I think better than the Duellers ). I went for the Kumho because the price was right, and they had proved themselves with other guys.
Mileage is dependent on the type of terrain you will be traveling on. On the beach sand in Mozambique, and Atlantis.... it eats the rubber ( but will do that on any tyre ).... on the rocks, you get the odd chunk of rubber carved out of the knobbly.
So overall I am happy with the performance!!
