Bristol Motor Speedway will once again use the PJ1 compound for a third consecutive time for this weekend's racing events there.

Look for PJ1 – or tire dragging to add more rubber to the racing surface – to be utilized at several other tracks during the upcoming 10-race NASCAR Cup playoffs.

"We had our driver council meeting Friday night in Michigan, and part of that meeting was to go over the remaining race tracks, talk about where we may or may not put something on the surface (or) where we want to rubber in the track," NASCAR Executive Vice President and Racing Development Officer Steve O'Donnell said Monday on The Morning Drive on Sirius/XM NASCAR Radio.

"(We) really worked with the drivers to say what is the exact line where you think this would continue to improve the racing on track," O'Donnell added. "It's been going really well so far.

It has worked so well that BMS sister tracks Charlotte Motor Speedway and New Hampshire Motor Speedway – which will both host races in the upcoming 10-race NASCAR Cup playoffs – have also utilized the compound.

At tracks that do not use the compound, O'Donnell said others may use tire dragging to add more rubber to the race surface, much like took place at Michigan International Speedway prior to Sunday's race. NBC Sports
