The new Option tire isn’t something Goodyear started completely from scratch. Tweaks to the set-up and compound were formulated from past experiences with the Prime tire, Stucker explained.
“The construction itself is the same between the Prime and the Option,” he said. “We made formulation changes to both the left side and right side. The left side is actually a known compound. It’s what we’ve raced at Fontana, Indy (up until this year) and Darlington. It’s a known quantity. We haven’t raced it at Charlotte, but we kind of know how it behaves. The right side is formulation change based on testing we’ve done historically.”
Goodyear then tested those new formulations and relayed that information to teams to give them a good basis for what to possibly expect.
“The formulations or similar have been tested at other places, so we kind of know what to expect with those adjustments,” he added. “The testing of the tire itself was done in the lab. Before every race, we do predictive testing for every combination that we run, and then we share that information with the teams.”
Overall, it was all about giving drivers a little more grip.
“It’s a known adjustment from the formulation itself to try to put a little more grip in that tire,” Stucker said. “Just getting a little grip out of both right side and left side. It’s a combination we haven’t raced, but it’s something we know about.”
The Prime tire is also the compound drivers will run in the Coca-Cola 600 on May 28 (5:30 p.m. ET, FOX).
