Bridgestone B381 145/45 R14 MG Morris 1000 20,000 miles May 5, 2013
Much better than previous aged Mitchelins. However, I had a sidewall fail and bludge/bald spot on the other side(both rear axle). (Possible cause: I never felt the back of my Morris needed wheel balancing!)

Who does the testing

Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
