Few names are as synonymous with professional off-road tyres as Cooper, and the American manufacturer has extended its reach in the segment in recent years via its relationship with the Dakar veteran Xavi Foj, made a brand ambassador. The latest tyre to be released by the manufacturer, the Discoverer S/TMAXX POR (Professional Off Road), as a tyre designed for 4×4 driving in extreme conditions, is one that is particularly relevant to Foj. Indeed, the driver commented on its introduction: “the Discoverer S/TMAXX POR is my tyre of choice, the most complete tyre for all uses – from daily tarmac to victory in the toughest terrain in the Dakar Rally.”
