Bridgestone announced today it has been chosen by Ferrari as a tire supplier for the Italian manufacturer’s latest GT car, the Ferrari Roma. With 620bhp and rear-wheel drive, Ferrari needed a tire that suited the Roma’s performance in both dry and wet conditions. A collaboration with Bridgestone has seen the ground-breaking Bridgestone Potenza Sport evolve to match the Ferrari Roma’s unique requirements.
Developed to deliver high-end performance
The Bridgestone Potenza Sport, which delivers best-in-class performance in the dry alongside outstanding wet weather grip, was custom-developed by Bridgestone to optimize lateral and longitudinal grip, as well as wet and hydroplaning performance.
In order to achieve such challenging targets, Bridgestone developed a dedicated top tread compound and rear tire pattern geometry-void distribution to retain the outstanding wet weather performance of the Bridgestone Potenza Sport, while retaining the tire’s dry handling capabilities. Dedicated development ensured that Bridgestone Potenza Sport provides the dynamic performance characteristics required. This included tuning the tread pattern design on the rear tires for optimal wet weather performance.
‘A fantastic case study for collaboration’
The custom-engineered Bridgestone Potenza Sport is now available on the Ferrari Roma in 245/35ZR20 91Y and 285/35ZR20 (100Y) sizes. The tire was developed and produced at the Bridgestone EMIA Technology and Innovation Center in Rome, Italy, which is dedicated to the production of high technology, specialized tires. Although the factory typically manufactures Bridgestone EMIA’s prototype tires, the Ferrari Roma project has seen it produce OE tires for the first time that will be directly fitted on the vehicle as it takes to the roads.
“Working with Ferrari on the Roma has been a fantastic case study for collaboration,” Steven De Bock, vice president Consumer Replacement and Original Equipment at Bridgestone EMIA. “We’ve worked together over a long, purposeful process to custom engineer an incredibly capable tire, in the form of the Bridgestone Potenza Sport, to meet the Roma’s high-performance demands. We’re proud of the result, with the bespoke Bridgestone Potenza Sport offering performance and handling attributes that maximize the Ferrari Roma’s capabilities.”
