Cup and Xfinity Series teams return to New Hampshire Motor Speedway this weekend and will compete on new right and left-side tires on the 1.058-mile track.

While the tires will feature the same tread compounds that were run at New Hampshire last year, they will have construction updates to bring this set-up in line with what is run at other tracks. This is the only track at which teams in either of these series will run these two Goodyear tire codes.

As on most NASCAR ovals 1 mile or less in length, teams will not run inner liners in their tires at New Hampshire.

According to a Goodyear press release, because of NHMS’ minimal banking, the track produces minimal load compared to more high-banked tracks. Because of that, grip needs to be generated through the compounds selected in Goodyear’s tire set-up.

Goodyear says both the left and right-side compounds run at New Hampshire are among the highest performing in its tire lineup.

Greg Stucker, Goodyear’s director of racing, cautioned teams against lowering the air pressure in their left-side tires below the minimum recommended inflation levels of 12 psi.

“Loudon has very little banking, so some teams try to enhance their level of grip by getting aggressive with their air pressures, most notably on the left-side of the car,” Stucker said in the press release. “Our recommended left-side pressures at Loudon are 12 psi, and teams have been known to drop well below that in the race.  Running below our recommendations are always a risk vs. reward proposition.  Air pressure provides structure to a tire, and running too low risks the sidewall over-deflecting early on in a run, which can lead to carcass fatigue and eventually an air loss.”

New Hampshire will treat its track surface with the PJ1 traction compound in all four turns this weekend.
