Storyline – The search for grip at New Hampshire: Being a relatively "flat" track, New Hampshire Motor Speedway produces minimal load compared to more high-banked tracks. Because of that, grip is generated through the compounds Goodyear selects for its tire set-up. Both these left- and right-side compounds have been changed since last year’s race and will add grip. Another factor is that teams will occasionally look to gain grip by going below Goodyear’s recommended air pressures. Low left-side pressures, which some teams run down into the single digits, can cause the sidewall to over-deflect and damage the tire carcass to the point of air loss.

"We have a different tire set-up at New Hampshire this year, and it is the same as what we run at Phoenix," said Greg Stucker, Goodyear’s director of racing. "This set-up has different tread compounds than we ran at Loudon last year, and teams should see a grip enhancement as a result. The real benefit is that Loudon and Phoenix are now aligned once again, which is how it had been in the past until Phoenix was repaved about a decade ago. This will give playoff teams another race with this set-up and will help them as they build their notebook for championship weekend in November."

Notes – Cup teams to run Phoenix tire set-up at New Hampshire: NASCAR Cup teams will run a different tire set-up at New Hampshire than they ran at this track last summer . . . these are not new tire codes – Cup teams ran this same tire combination at Phoenix in March . . . compared to what was run at New Hampshire last season, this tire set-up features compound changes on both sides of the car and a construction update on the left-side . . . the compound changes will give the cars more grip and introduce more wear . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at New Hampshire.
