Goodyear's extended mobility technology (EMT) tire can run flat for 93 miles at 50 mph. But what does that do to the wheel? That's the question University of Akron PhD student John Stearns researched. He used ALGOR (www.algor.com) finite element analysis software to get the answer. Result: No damage to a standard wheel. Stearns did learn, though, that the highest stresses were at the lowest pressures.
