In June 2022, Bridgestone will start selling the new Potenza Race semi-slick tire, homologated for road use but built primarily for those who love to test their supercars on the track. The ‘Race’ model is the latest addition to the Potenza tire line, based on Bridgestone’s rich experience in Formula 1, and was previously fitted as original equipment to the Lamborghini Huracan STO supercar and Seat Leon Cupra.
The tires were tested by TÜV SÜD experts and compared with direct competitors, namely Goodyear Eagle F1 Supersport R, Michelin Pilot Sport Cup 2 Connect and Pirelli P Zero Trofeo R, at the Bridgestone test site near Rome and also on the circuit of Nardo. In tests, Bridgestone’s new semi-slick tire allowed for the best lap time, at the same time it allowed the car to brake in less dry space than tires on the market. In terms of track duration, he finished in second place, behind only Goodyear’s Eagle F1 Supersport Rs.
The new Bridgestone tires feature an asymmetrical tread pattern with different external and internal zones, designed to improve lateral stability in dry conditions and braking performance, while ensuring adequate use even on wet roads. The angled walls of the grooves improve lateral tread stiffness and reduce the deformability of the blocks, while the rear axle tires feature a special design with a larger shoulder rib for improved ride quality and dry braking distances. short. The tires also have an optimized profile that increases the contact patch and improves braking performance, as well as facilitating control of the car at high speeds. In addition, the special compound was made using a new compounding process designed to improve the control of chemical reactions.
The Potenza Race was developed using virtual simulation technology to create and test a digital version of the tire and predict how it would perform in various conditions prior to prototyping. Thanks to this, engineers can test many more options in virtual reality and the time required for development can be reduced by up to 50%. Additionally, as fewer physical prototypes are required, resource use is reduced, which is environmentally beneficial.
Bridgestone Potenza Race is developed and manufactured in Europe. The line will include 13 popular sizes ranging from 17-20 inches in diameter, designed for the sports cars most used by track day enthusiasts.
