I drive a Land Rover Discovery TDV6 and bought my 255/60/R18 112H XL Scorpion A/T + tires on 313,000km. I do off-road trips with my club although recently not so much and the tires worked great. They are quiet on the road and perform off-road remarkably well although in sand driving especially on high sand dunes, the tires are not really suited for that although the vehicle is heavy which may have something to do with that as well but otherwise, I could go wherever I wanted.
The downside is that after just 50,000km, the tires started delaminating causing a dangerous situation for myself and my family. I was advised to change them as I could have a blow out at any time. This was happening on three of my four tires and after phoning Pirelli, I was bascially told that unless I can produce records of my tire rotations, they would even entertain looking at the tires. I orginally bought Pirelli tires because I expected backup service and by not getting it, I simply took off the tires and trashed them although there was still good tread on them.
I have switched to Dunlop and what a difference, it feels like I am driving on silk now. Sorry Pirelli, but your service stinks, at least here in South Africa.
