Exploding Dunlop rear tires sent both Steve Crevier and Jeff Williams tumbling down the back straight at Mosport last weekend, during a Canadian Superbike weekend.

Williams crashed during Saturday’s Superbike race and Crevier crashed during Sunday’s Superbike race. Both were in top gear when they crashed; Williams had completed six racing laps and eight total laps on his tire when it failed, and Crevier had finished six racing laps and seven total laps on his tire when it failed.

Williams was running a medium compound tire and Crevier was on a soft.

Weather conditions were constantly changing throughout the weekend, alternating thunderstorms with very hot ambient temperatures.

Both Williams and Crevier escaped serious injury, although Crevier crashed earlier on the “straight,” which actually has a kink in it, and clipped a wall, leaving him more battered and bruised than Williams, according to eyewitnesses.

Canadian Superbike rules require the use of stock wheels, which means that both Williams and Crevier were running 17-inch Dunlop radial slicks on their Diablo Suzuki GSX-R1000s.

Roadracingworld.com could not reach Crevier or Williams for comment. At post time, series organizer Colin Fraser had not returned a call requesting comment.
