Goodyear has revealed its tyre specifications for the 2019/2020 FIA World Endurance Championship (WEC) opening round at Silverstone. The race, on September 1st, marks Goodyear’s global racing comeback and the tyre company has developed four all-new tyre specifications to begin the 8-round WEC season.
Three top WEC teams (Jota Sport, Jackie Chan DC Racing and High-Class Racing) have chosen to race on Goodyear tyres in the highly competitive LMP2 class for high-downforce prototype cars. At Silverstone this will be the only WEC class to feature open tyre competition.
All-new approach for ultimate dry performance
The WEC regulations allow tyre manufacturers to supply a range of up to three dry-weather tyre specifications to racing teams for the season and Goodyear has chosen their first two specifications after an extensive 12,000km of testing at seven circuits.
At Silverstone, Goodyear will offer their A (softest compound) and C (medium compound) specification tyres to the three teams. These both feature brand-new constructions designed to offer driveability and consistency across the varied season of WEC circuits.
“With races lasting between 4 and 24 hours, our focus was to develop a range that had the versatility and performance to cope with varying temperatures, stint length between pit-stops and cater for the needs of a wide range of driving styles,” explained Mike McGregor, Manager Race Sales, Testing & Track Support.
Looking ahead to Silverstone, the new track surface is expected to have a major impact on race strategy: “Testing has shown that recent resurfacing has created a very high grip circuit that puts heavy loads through the tyres. We’ve also noticed the surface takes longer to ‘rubber in’ after rainfall which is one of the reasons we’ve chosen softer compounds to give drivers the confidence to push hard on new tyres after a pit-stop” added Mike.
Due to the resurfacing, the FIA has relaxed the regulations to allow teams to use an additional set of tyres during the event. This change is expected to turn the four-hour race into a series of flat-out sprints between pit-stops.
Wet focus - new technologies introduced
Goodyear’s LMP2 wet features a dramatic new tread pattern with curved grooves in the shoulder to dispel water at high speed but with a large continuous centre rib to retain stability and grip under heavy cornering loads. This design is inspired by Goodyear’s latest Eagle F1 SuperSport range for ultra-high-performance road cars.
The intermediate tyre actually features the same construction as the A-spec dry tyre to enhance its grip changing wet to dry conditions. This versatility allows the teams to optimise stint lengths between pit-stops.
Goodyear’s testing encompassed seven different circuits with the goal of testing in as many different wet conditions as possible. In addition to the English circuits of Silverstone, Donington and Rockingham, Goodyear also headed to Northern Ireland to Bishopscourt before testing at Portimao (Portugal), Motorland (Spain) and Sebring (USA).
