Goodyear Eagle F1 SuperSport RS homologated for Porsche 911 GT2 RS & GT3 RS
Porsche has homologated the Goodyear Eagle F1 SuperSport RS – the most race-focused member of the new Eagle F1 SuperSport range, for the 911 GT2 RS and Porsche 911 GT3 RS. This approval covers the sizes 265/35 ZR 20 (99Y) XL and 325/30 ZR 21 (108Y) XL. The homologated Goodyear Eagle F1 SuperSport RS tyres bear the Porsche N0 marking and will be sold through the Porsche dealer network.
Jan Frank, lead engineer at Porsche Motorsport, comments on the new tyre: “The new Goodyear Eagle F1 SuperSport RS has proven to provide the very high-performance level which we from Porsche require. Goodyear has designed a great tyre for us which perfectly fits into the extreme requirements of our Porsche 911 GT2 RS.”
The Eagle F1 SuperSport RS marks Goodyear’s return to the Ultra Ultra High Performance (UUHP) market segment. “In development of the SuperSport RS we have leveraged our talented engineering teams and world class development facilities to produce a world-beating UUHP tyre,” says Nick Harley, managing director of Goodyear OE in the EMEA region. “The tyre is designed to enhance the performance and handling characteristics of the most specialist machinery on the roads today and in vehicle manufacturer’s development pipelines.”
Goodyear comments that Porsche Motorsport’s usage remit for the GT2 RS was “particularly challenging”. It required the 265/35ZR20 (99Y) XL (front) and 325/30ZR21 (108Y) XL (rear) tyres to transmit 700 hp and 750 Nm through the wheel wheels with optimal efficiency, a challenge compounded by peak torque arriving from just 2500 rpm.
“The list of tyres truly competitive in these conditions is short,” continues Harley. “For the Eagle F1 SuperSport RS to receive the praise it has from a manufacturer with as relentless a pursuit of improvement as Porsche, truly reflects how far Goodyear has moved the UUHP segment on.”
Goodyear developed the Eagle F1 SuperSport RS specially for Porsche Motorsport, with a brief to facilitate record performance on track.
Xavier Fraipont, vice president EMEA Product Development for Goodyear, is bullish about the tyre’s capabilities: “Goodyear has a great heritage in motorsport. Now we bring all our experience and knowledge into the new Goodyear Eagle F1 SuperSport RS, developed in Europe to increase performance level of super sport cars, with main focus on all track day performances.”
Pioneering UUHP developments
Benefitting from exhaustive development at Goodyear’s Development Centre Hanau, Germany where more hundreds of engineers, scientists and technicians work on new materials, tread designs and manufacturing techniques, the tyre maker says its Eagle F1 SuperSport RS brings “a number of pioneering developments” to the UUHP market:
A pure racing compound maximises dry grip by combining very stiff tread elements with a reduced tread depth. The combined benefit helps maximising the g-forces while minimising movement of tread pattern in extreme cornering conditions, this providing the driver with both maximum grip level and extremely precise steering behaviour.
The adapted tyre construction utilises further lessons from motorsport and bestows the Eagle F1 SuperSport RS with an optimised tyre profile to increase size of contact in combination to strong Aramid winding to keep the pressure distribution constant in different driving conditions and at different speeds.
Finally, the tread design features a massive outer shoulder which has been designed to optimise transmission of all lateral forces and facilitate extreme cornering stability.
