What is the difference between the two? Does the desert IT just have a stiffer carcass? Who has tried both? I have been reading good things about them, I might try one. I am a little worried about getting any tyre other than a Dunlop 952 as they last so long and are really awesome in all conditions. How do they compare to the 952? Tyres cost about the same here in Australia, so price is not a factor at all.
