Story – Several factors affect tires in Bristol: The NASCAR Cup Series concludes the first round of qualifying this weekend at Bristol Motor Speedway, and both teams and tires will face a tough challenge. The concrete surface in Bristol is tough on the tires and will constantly change as the race continues for more than 500 laps. Because of the speeds and loads, Goodyear tailors its Bristol tires to align with other highways, not the short trails a half-mile length would suggest. From the point of view of the tread assembly, the key to Goodyear is to put the rubber on the concrete surface. This, combined with the fact that the PJ1 grip compound will be applied to several lower feet of the racing surface at both corners, will allow drivers to move up the track to find alternate grooves as they search for grip.

“Bristol is without a doubt an overarching challenge,” said Greg Staker, Goodyear Racing Director. “We did a good job bringing a set of rubber into the track and allowing for multiple racing grooves. Bristol has a recent history of using the PJ1 in corners, so the ‘favorite’ groove takes the rubber out fairly quickly. Progressive banking and the search for new concrete will drive the teams up to the right track, which could lead to more passing and better racing.”

Notes – Trophy teams on the left side of Pocono and the unique right side of Bristol: After moving to an 18-inch beadlock tire for 2022, NASCAR Cup teams will be running a different set of tires than those on the Xfinity and Truck Series in Bristol this week. . . These are the same left-sided Tire Cup teams that ran at Pocono in July. . . This is the first time these teams have run this right frame icon. . . In addition to the obvious structural changes of what the Cup teams made in last year’s race on Bristol concrete, these two tire codes feature composite changes, giving the cars more stability. . . With this 18-inch tire, lower sidewall, NASCAR Cup cars will not run the inner bushings on any of their tires in 2022.

Notes – Xfinity Teams, Truck on Bristol’s famous left side tire: Featuring 15-inch diameter tires, the NASCAR Xfinity and Camping World Truck teams will be running a different set of tires than those in the Cup Series in Bristol this week. . .
