Kumho covers all bases

Kumho is covering covers all bases with its latest trio of high performance tyres.


The PS91 is Kumho’s optimum high-performance road product, that’s achieving a good level of sales in the UK market. 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 is Y or (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 have any of these qualities been achieved at the expense of other key factors, and the Ecsta PS91 features a specially designed sidewall that suppresses vibration to improve comfort and reduce noise. It also has a 3D dimple design which cools the tyre at high speeds, optimising durability and wear rates.


The relative newcomer to Kumho’s excellent trio of high-performance tyres, the asymmetrically-patterned PS71 was one of the first major products to be developed at the company’s new R&D Centre at Yongin near Seoul, South Korea, and has now effectively replaced the ever-popular ECSTA KU39. PS71 has been designed for outstanding high-speed stability and strong wet weather performance. Thirty sizes are already on sale and the pattern will ultimately be available in 37 Y-rated sizes from 17 to 20 inches in diameter – ie to fit the market’s best-selling executive saloons and sports cars. In addition, PS71 will soon be available in a comprehensive range of run-flat sizes.


Another fairly recently-introduced high-performance offering from Kumho, the ECSTA HS51 was highly praised in the recent Auto Express summer tyre test. It topped the wet cornering discipline, was placed second for cabin noise, and third for wet braking. Ultimately, the Kumho was only beaten by products from Continental, Dunlop and Bridgestone and was judged to be the ‘best of the mid-range brands’. It had previously been awarded a ‘recommended’ rating by the highly-regarded German consumer magazine ACE Lenkrad, where it was again accorded a ‘strong wet road performance’, having scored the highest marks of all 12 tyres on test when it came to the event’s aquaplaning and wet braking challenges. The ECSTA HS51 features a solid rib-type design for improved wet road braking, four prominent circumferential grooves for optimum water displacement, and wide lateral ones for enhanced wet weather steering. HS51 is available for 15 to 18 inch rims, in widths from 185 to 245mm, and V and W speed ratings.
