ELKHART LAKE, Wisconsin — For only the third time in NASCAR history, cars are racing on wet weather tires in Saturday afternoon’s Gardner Denver 200 at the Road America road course.
The 50-lap race around the 4.048-mile 13-turn track was brought under caution on Lap 25.
Drivers made two more laps around the track under caution before NASCAR officials mandated that all cars stop on pit road on Lap 27 and that installation of the so-called rain tires was mandatory, not an option.
The race remains under caution heading to Lap 28 and is expected to go green on Lap 29.
This is the third time NASCAR cars have raced on rain tires: the other two times were in Nationwide Series races in 2008 and 2010, both in Montreal.
UPDATE: The race is back underway with 22 laps left and Sam Hornish Jr. in the lead.
Alex Tagliani took the lead away from Hornish on the following lap and remains at the front of the field with 19 laps left in the race.
