I drive a Land Rover Discovery TDV6 and bought my 255/60/R18 112H XL Scorpion A/T + tyres on 313,000km. I do off-road trips with my club although recently not so much and the tyres worked great. They are quiet on the road and perform off-road remarkably well although in sand driving especially on high sand dunes, the tyres 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 tyres 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 tyres and after phoning Pirelli, I was bascially told that unless I can produce records of my tyre rotations, they would even entertain looking at the tyres. I orginally bought Pirelli tyres because I expected backup service and by not getting it, I simply took off the tyres 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.
