I am on my second set of Coopers, never changing to another brand.
In ten years, no puntures, no side wall damage and they pull the Hilux up quickly and under control. I put then on the work cars in my old job, improved the handling of a F150 V8 351 and Suberben 6.8 litre Turbo Diesel.
Yes, they have been off road, sand, mud and rock.
