Burning rubber: Clint Bowyer, Dale Earnhardt Jr. post blazing speeds at Michigan tire test

A few NASCAR drivers are tire testing at Michigan International Speedway … and they’re burning some serious rubber. 

Clint Bowyer says he hit 217 mph.

DeLana Harvick has another word for it. 

Dale Earnhardt Jr. wasn’t far behind.

Blazing. But what does it mean for the June Sprint Cup race at MIS?

With the way things have been going this season, Joey Logano’s track qualifying record of 203.949 mph could be in serious jeopardy.
