In this test, we were excited to put the DriveGuard Plus, featuring Bridgestones latest generation run flat technology to the test. Bridgestone designed the DriveGuard Plus to compete head-to-head with the finest touring tires on the market with no caveats or excuses. With this claim, we knew we weren’t going to take it easy on this tire! We chose two of the most comfortable touring tires on the market as benchmarks for this test.
