Storyline – Cup teams manage 12 sets of tires as fresh rubber matters at Charlotte: Monster Energy NASCAR Cup teams will be running the same tire set-up for the Coca-Cola 600 that they ran during All-Star weekend at Charlotte. Based on the racing last weekend, tires will be a factor. First, All-Star teams that took four tires overcame the track position of those that did not. Second, with 12 race sets of tires for NASCAR’s longest race, the pit crews will play a big part in a team’s success, and those that master all those four-tire pit stops will help their car gain valuable spots on pit road.
“The Coca-Cola 600 is the longest race on the schedule and it is held on one of the more temperature sensitive tracks upon which we compete, as the race starts in daylight and ends at night,” said Greg Stucker, Goodyear’s director of racing. “We saw that fresh tires mattered last weekend during the All-Star race. Four tire pit stops should be the order of the day and teams have 12 sets of tires for the 400-lap race, so the team aspect of the sport will be on full display as the pit crews will be kept busy all night.”
Notes – Cup cars on same tire set-up as All-Star weekend: Teams in both the NASCAR Cup and Xfinity Series will run the same tire set-up at Charlotte this week . . . this is the same combination of left- and right-side tires that Cup teams ran during All-Star weekend last week . . . for the Cup cars, this is the same right-side tire code they ran in last year’s Coca-Cola 600 and the same left-side tire they have run the last three weeks – Dover, Kansas and All-Star . . . for the Xfinity cars, this is the same right-side tire they ran on the Charlotte oval in 2018, combined with their 2019 Dover left-side tire . . . compared to what was run at Charlotte last year, this left-side features a construction update to align it with what is run at other speedways . . . this tire set-up came out of a test on the 2019 rules package that was run at Charlotte last October . . . teams (drivers) participating in that test were Richard Childress Racing (Daniel Hemric), Joe Gibbs Racing (Erik Jones), Hendrick Motorsports (William Byron) and Stewart-Haas Racing (Aric Almirola) . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
Goodyear debuts special “Honor and Remember” sidewall at Charlotte: Since 2010, for one weekend per NASCAR season, Goodyear has changed the branding on the sidewall of its racing tires in a show of support for the United States military and fallen heroes. This being the 10th year of that program, the official tire supplier to NASCAR’s top three series will work with a new organization and replace the standard “Eagle” with “Honor and Remember” for both the Monster Energy NASCAR Cup and NASCAR Xfinity Series races.
Honor and Remember is a national organization based out of Virginia that has a mission to “perpetually recognize the sacrifice of America’s military fallen service members and their families,” according to its website. The organization recognizes fallen military personnel from all wars or conflicts, and with those from all branches of service. They do so primarily by dedicating the specially designed Honor and Remember flag, which is intended to fly continuously as a tangible and visible reminder to all Americans of the lives lost in defense of our national freedoms.
