The race is on: consumers who buy four new Yokohama tires from now through Sept. 30 will get a free entry into a 2018 or 2019 Spartan race, valued up to $190. Spartan is world’s largest obstacle race and endurance brand.

“Talk about a ‘strong’ promotion,” said Alan Holtschneider, Yokohama’s director of marketing. “Not only do consumers get a free entry to compete in a super-tough Spartan Sprint, Super or Beast race in the 2018 or 2019 season, they also get a great set of tires.”

Yokohama is the Official Tire of Spartan U.S. Yokohama also is a sponsor of the 2018 Spartan World Championship, Spartan Pro Team competitors Faye Stenning and Robert B. Killian Jr., and adaptive athletes Misty Diaz and Jonathan Lopez.

Yokohama tires are used by Spartan race participants competing on the obstacle course in the “Yokohama Tire Flip,” a true test of conditioning and strength. Spectators also get in on the action by stopping at Yokohama’s booth at each race to try their tire-flipping ability as part of the Yokohama Tire Flip Festival Challenge.
