Kyle Busch speaks out about his unique find at North Wilkesboro ahead of All-Star Race

Kyle Busch shared insights about his experience at North Wilkesboro Speedway after competing in the Truck Series Window World 250 ahead of the 2025 NASCAR All-Star Race.

Busch explained that he entered the Truck Series race to get a better feel for the track before the All-Star event, but discovered that the racing lines between the two vehicles were notably different. In the truck, he found himself running a much higher line, right up against the wall in the corner, while in the Cup car, the preferred line was a lane lower. Speaking to NASCAR journalist Peter Stratta, Kyle Busch said:

"It's funny because the truck line that I was running was super high; enter right up on the wall, get it to the wall in the middle of the corner, and then the cup car was, was, a lane, lower, you know, so just different between the two vehicles. So, what I learned in the truck race didn't do a whole lot," he explained [00:05].

As a result, Kyle Busch concluded that what he learned in the truck did not translate to the Cup car, making his unique approach from the Truck Series "not viable" for the All-Star Race itself.
