Video: Bridgestone's new DriveGuard run-flat tire

AUSTIN, Texas (April 11, 2014) — In this video, Robert Saul, product planning manager at Bridgestone Americas, details the features of the DriveGuard line of run-flat tires for the replacement market that was launched recently at a ride-and-drive event at the Circuit of the Americas near Austin.

Mr. Saul said while all drivers can benefit from the new run-flat technology, safety-conscious drivers will really appreciate it. The DriveGuard features run-flat technology that gives drivers the ability to continue driving up to 50 miles at maximum speeds of 50 miles per hour if a puncture or loss of pressure should occur.

Features of the DriveGuard include: cooling fins that disrupt the airflow and disperse heat, thus cooling down the tire; a high-silica tread compound used on Bridgestone's Turanza Serenity Plus to improve traction in wet conditions and provide better wear; and Bridgestone's Nanopro-Tech rubber compound that reduces friction between carbon molecules, reducing heat generation.
