Storyline – High-wear Homestead leads to great racing: Homestead-Miami Speedway has become one of the more high tire wear tracks on the NASCAR circuit. High wear tracks bring tire management into play, with some drivers gaining spots early in a run while others gain later by conserving their tires and having more long-run speed. While the amount of fall-off during a run at Homestead is more than two seconds per lap, the rate of that fall-off may be different for everyone. That ultimately has a positive effect on the racing as it creates more passing throughout the field. That, combined with Homestead’s progressive banking and the pressure of championship weekend, always makes for great racing as NASCAR concludes its season for all three of its national series.

“Homestead is one of the highest tire wear tracks that we have on the NASCAR circuit,” said Greg Stucker, Goodyear’s director of racing. “We have a new tire set-up for Homestead, and it is the same one we ran at both Chicagoland and Darlington earlier this season. The compounds we will be running provide plenty of grip, but also offer the endurance needed on Homestead’s track surface. These high wear tracks put on some of our best races, and the past several years at Homestead have proven that. Tire fall-off creates more ‘comers’ and ‘goers’ over the course of a long run, which means more passing and tire management being an important element of the race. Also a factor is how the teams’ pit crews come into play with 12 sets of tires for the race and four-tire stops all day.”

Notes – All three NASCAR series on Chicagoland/Darlington tire set-up at Homestead: Teams in all three NASCAR series will run the same tire set-up at Homestead this weekend . . . this is the same combination of left- and right-side tires that all these teams ran at Chicagoland and those in the Cup and Xfinity Series ran at Darlington this season . . . this is a different set-up than the one run at Homestead in 2018 . . . compared to what was run at this track last season, both this left-side and right-side tire feature construction updates to align with what is run at other speedways, while this right-side takes teams from a multi-zone tread tire to a single zone tire and will increase grip . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Homestead . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
