In an update to the rule book, NASCAR is adding tire tests Aug. 14-15 at Texas Motor Speedway and Oct. 2-3 at ISM Raceway in Arizona.
The Texas tire test is scheduled to have a team each from Hendrick Motorsports, Richard Childress Racing, Stewart-Haas Racing, Team Penske and Furniture Row Racing. The test is to determine tires for the fall playoff race at Texas.
The Phoenix test is scheduled to have a team each from Chip Ganassi Racing, Wood Brothers Racing, Roush Fenway Racing and Joe Gibbs Racing. That test is set to find a tire combination for the 2019 races there.
The Atlanta Motor Speedway tire test will now be Oct. 16-17. It was pushed back from Aug. 14-15.
Also in the rule bulletin:
Effective July 11 in the Camping World Truck Series, NASCAR will use owner points instead of attempts to qualify in determining provisionals.
Also, when Truck qualifying is canceled, two spots (positions 26 and 27 in the lineup) will be awarded based on the fastest combined practice speeds to vehicles not yet assigned a starting spot. The top 25 spots will be determined by owner points. Filling out the final spots will remain the same as stated in the rule book.

DOVER, Del. — Rookie Chase Briscoe’s crew chief, front tire changer and front tire carrier each face the prospect of a four-race suspension after the left front tire rolled off during Friday’s NASCAR Camping World Truck Series race at Dover International Speedway.
Section 188.8.131.52.3.c of the series rule book states: “Loss of wheel(s) due to improper installation will result in a mandatory minimum four Race suspension of the crew chief, tire changer and tire carrier of the lost wheel(s).’’
NASCAR called crew chief Mike Hillman Jr. to meet with series officials after the race.
Hillman said the team had no lug nuts attached to the left front when the jack was dropped, signifying for Briscoe to leave his pit stall, which was closest to pit exit.
“I think the (air) gun was in reverse,’’ Hillman said. “Being in the first stall … you don’t have a chance to stop on pit road and fix it. You’re hollering ‘Stop! Stop! Stop!’ When he stops, the tire came off.’’
Hillman understands the rule and what he likely will face.
“It’s a safety thing,’’ he said. “We’ll see what NASCAR has to say and work through it.’’
Any penalties are expected to be announced next week.
Should NASCAR enact the suspension, Hillman, the tire changer and tire carrier would miss races at Texas Motor Speedway (June 9), Gateway Motorsports Park (June 17), Iowa Speedway (June 23) and Kentucky Speedway (July 6). They’d be eligible to return for the July 19 race at Eldora Speedway.
Briscoe, who started on the pole, finished 12th for Brad Keselowski Racing.
