Lack of Banking Puts a Premium on Grip at New Hampshire: Being a relatively “flat” track, New Hampshire Motor Speedway produces minimal load on right-side tires compared to more high-banked tracks. Because of that, grip needs to be generated through the compounds selected in this Goodyear tire set-up. Both the left- and right-side compounds run at New Hampshire are in the top-three highest performing used in the 2017 tire lineup. One other factor in play this weekend is that because of a lack of banking for cars to lean on, teams look to gain grip in other ways, namely by going below Goodyear’s recommended tire pressures. The left-side pressure recommendation for New Hampshire is 12 PSI, and there have been times that teams have dipped into single digits.
“Teams are always in search of grip at New Hampshire,” said Greg Stucker, Goodyear’s director of racing.
“To help with that, we bring some of our most tractive compounds to this track, not only because of its short track characteristics but also because of the lack of banking. Teams often try to gain more grip by pushing the envelope on our recommended air pressures. At New Hampshire, our left-side recommendation is just 12 psi, and only Martinsville has a number lower than that. The risk is that if teams go too low, specifically on the left-sides, they over-deflect the sidewall, which can lead to carcass fatigue and eventually air loss.”
Teams in both the NASCAR Cup and Xfinity Series will run the same tire set-up this weekend. The teams have run this left-side tire (D-4564) at New Hampshire since 2012 and this right-side tire (D-4706) debuted at this track in July 2016. New Hampshire is the only track at which teams in either of these series will run these two tire codes. As on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at New Hampshire.
Upcoming Tire Test: Goodyear will hold a tire test at Darlington Raceway next Tuesday (July 18). Teams scheduled to participate in that test are the No. 2 Penske Racing Ford (Brad Keselowski), No. 31 Richard Childress Racing Chevrolet (Ryan Newman), No. 42 Chip Ganassi Racing Chevrolet (Kyle Larson) and No. 77 Furniture Row Racing Toyota (Erik Jones).
