CONCORD, N.C. -- Before heading off to take part in a wedding during the off weekend, Dale Earnhardt Jr. had one piece of business to attend to.

Earnhardt shared the experience on Twitter, even jokingly blaming a freshly trimmed beard for some scrapes on the car afterward.

Earnhardt represented Hendrick Motorsports at the Goodyear tire test.

"It's an opportunity for the teams to really dial in the tire and the aero package for '15," NASCAR Executive Vice President and Chief Racing Development Officer Steve O'Donnell explained on SiriusXM NASCAR Radio. "Certainly an important event for just about everybody in the series so they'll be going down there, working with Goodyear to make sure they've got the right package to be able to obviously share that data with the race teams and get ready for the final push that we see in November."
