I have had four flats in less than three years. One was caused by a road hazard, the others sidewall failures. My friends have had similar experience.
The OEM Goodyears on Gen 1 Volts are made of Kleenex. The fact that some posters have managed not to experience this does not mean they are OK. The large number of posters reporting problems shows there was a problem. As does the fact that GM dumped them for Gen 2
My solution was to buy a warrantee from America's tire after the first sidewall failure. All the rest they replaced for free.
