GENEVA, Switzerland — Goodyear and Group Michelin have launched tires designed for dual track and street use, products defined as "ultra-ultra high-performance (UUHP) tires.
Both tire makers showed their entries in this hyper-performance category at the recent Geneva International Motor Show.
Goodyear rolled out an Eagle F1 SuperSport series comprising three models — SuperSport, SuperSport R and SuperSport RS — while Michelin displayed its Pilot Sport Cup2 R for maximum grip on dry circuits.
Goodyear said the SuperSport series tires deploy "innovative" technologies and compounds that enable measurable improvements in braking distances and lap times without neglecting more intangible elements of the driving experience, such as feedback during turn-in, under braking and approaching breakaway.
The SuperSport features stiff tread ribs for responsive directional changes while a closed tread pattern on the tire's outside shoulder provides control during load transfers in corners. A stiff sidewall design further improves handling without unduly compromising ride comfort, Goodyear said.
Wet performance is addressed through the deployment of dry-optimized tread compound on the tire's outer sections paired with three wet-optimized central segments.
Goodyear is rolling out F1 SuperSport through May in 25 sizes covering fitments ranging from 18 to 21 inches in rim diameter, 205 to 305 mm widths and aspect ratios of 45 to 30.
The SuperSport R offers increased grip levels and steering precision through use of a high-friction compound and bridges in the tread pattern's inner groove that reduced deformation of tread blocks under extreme cornering forces. Steering precision and feedback also have been further enhanced by optimizing the tire's footprint for more consistent pressure distribution.
