Storyline – Gateway tire set-up aligns with short tracks: While World Wide Technology Raceway is 1.25 miles in length, it falls into the same Goodyear tire grouping as the NASCAR short tracks.  With new Cup tire set-ups for that style track this season – featuring a thicker tread package – these teams have already run this weekend’s set-up despite it being new to this track.  Cup teams have already run this same tire combination at Phoenix and Richmond in March.  Goodyear moved to the thicker tread (gage) at Martinsville Speedway in the fall of 2023 in a move to increase lap-time fall-off over the course of a run.  More gage keeps more heat in the tire, thus leading to more fall-off.

“Since Gateway joined the Cup schedule back in 2022, it has fallen into our group of short track set-ups,” said Greg Stucker, Goodyear’s director of racing.  “We’ve been working on our tire set-ups as the sport has continued to make adjustments to the short track package with this Next Gen car.  We first increased the gage in the Martinsville set-up last fall, and that’s the direction we’ve continued to go with Phoenix and Richmond earlier this season and now at Gateway.  A thicker gage allows less heat to dissipate through the tire’s tread, and that will cause more fall-off over a run.  Since Cup teams have run this same set-up twice already this season, they have a good playbook started and will know what to expect.”

Notes – Cup teams to run new Phoenix/Richmond tire set-up at Gateway: Being on an 18-inch bead diameter tire, NASCAR Cup teams will run a different tire set-up than those in the Craftsman Truck Series at Gateway this weekend . . . this is a different combination of left- and right-side tires than Cup teams ran at Gateway last season . . . compared to 2023, these tires have more gage (tread thickness) to align with similar tracks on the circuit . . . Cup teams have run this same tire set-up at Phoenix and Richmond in 2024 . . . with this 18-inch tire and its lower profile sidewall, NASCAR Cup cars do not run inner liners in any of their tires.

Notes – Trucks return to Gateway on established tire set-up: Being on 15-inch bead diameter tires, NASCAR Craftsman Truck Series teams will run a different tire set-up than those in the Cup Series at Gateway this weekend . . . this is the same combination of left- and right-side tires Truck teams ran at Gateway the last two seasons . . . this is also the same tire set-up these teams ran at North Wilkesboro two weeks ago, and have run at Indianapolis Raceway Park, Phoenix and Richmond since 2022 . . . as on all NASCAR ovals greater than one mile in length, Truck teams are required to run inner liners in all four tire positions at Gateway . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Wet Weather Tires – White-lettered tires on hand: Goodyear will bring its 15-inch wet weather radials to Portland for use by Xfinity Series teams, should NASCAR decide that conditions warrant . . . teams will have 5 sets of wets available for the event, with a maximum of 4 sets for the race . . . Xfinity teams last ran in wet conditions on the Indianapolis road course last August . . . these teams ran in wet conditions at Portland in 2022 . . . in addition to the obvious difference of a tread pattern versus Goodyear’s dry weather “slick” tires, the “Goodyear” and “Eagle” lettering on the sidewalls of the wet weather tires is white, not the standard yellow.
