After a year of short-track tire experiments aimed at solving the Gen-7 car’s deficiencies at short tracks, what have we learned? And how will that knowledge affect the penultimate race of the season at Martinsville this weekend as six drivers compete for the last two spots in the Championship 4? […]
The Bristol 2024 race set lead change record for short tracks, but only because of abnormal tire wear. Let’s investigate why. […]
Not even the most talented publicity person could convince NASCAR fans that the idea of giving teams a choice of a ‘soft’ tire and a ‘regular’ tire was a good idea based on the sole […]

Will 2017 Tire Limit Rules Require Harder Tires? Back in the day, the only thing that limited how many sets of tires you could use in Cup-level racing was your budget. It was different in […]

Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points.
