The three-day Dunlop tire test at Daytona International Speedway has ended one-day early for 1000cc Superbikes and Superstock bikes.

Following a rear tire failure on Jason DiSalvo’s Yamaha YZF-R1 Superstock bike and the resulting high-speed crash Tuesday at the Speedway, Dunlop asked teams to return all slick tires Wednesday morning, according to members of several teams.

Dunlop representatives were in a meeting at post time and unavailable for comment but are expected to release a statement later today.

Teams with Supersport bikes, like Yamaha, have said they will continue testing Wednesday on their 600cc machines.
