Kumho reports that it’s Ecsta PS91 is now only weeks away from UK availability. The PS91 is positioned as Kumho’s optimum high-performance road product, sitting above the ever-popular Ecsta Le Sport KU39. Squarely aimed at supercars and such ultra-quick passenger saloons as BMW M cars, Mercedes-Benz AMG models and Audi RS ones, the entire range will be Y-rated and offered in sizes from 18 to 20 inches in diameter. The focus is on maximum grip and braking performance in the dry, combined with outstanding feel. Nor – says the company – have any of these qualities been achieved at the expense of other key factors. It also has a 3D dimple design which cools the tyre at high speeds, optimising durability and wear rates.
