Alcoa Wheels has launched the #5lbPledge social media campaign and contest.

The four-week event, which takes place on Twitter at @AlcoaWheels, will highlight the importance and benefits of healthy living through shared content and tips on achieving a fit lifestyle, according to the company.

#5lbPledge, which runs through Sept. 25, is a connection to Alcoa’s lightest and strongest heavy-duty truck wheel on the market, the Ultra ONE wheel with MagnaForce alloy. The 40-lb. wheel weighs five pounds less than its highest volume wheel, enabling fleets to lower truck weight, increasing payload and fuel economy while lowering maintenance costs, Alcoa said.

For the wheel, losing five pounds resulted in an overall better “lifestyle,” so the company said it wants to encourage others to better themselves through expert information and allow followers and participants to showcase their journeys and tips to healthy success.

Alcoa Wheels urges social media followers and contestants to follow the company on Twitter (@AlcoaWheels) and snap eligible photos and/or video of their healthy lifestyle tips and success stories. Participants should tag the images with the hashtag #5lbPledge. Completing these steps will result in automatic entrance into the official contest.

Prizes will be awarded every Friday corresponding to that’s week’s theme. When the campaign and contest officially closes, Alcoa will evaluate all photos and videos and announce a Grand Prize winner, who will receive a pair of Alcoa Ultra ONE wheel with MagnaForce alloy.
