Thank you for the comment. I think that it is fair to say that tires that don’t go flat in general would be great for most consumers! There are already run-flat tires out there on which consumers can drive up to 50 miles and that technology should only improve over time. Also, if you haven’t heard, Bridgestone recently introduced an air-free tire prototype http://techcrunch.com/2011/12/07/video-bridgestone-showcases-airless-tire/. As you can imagine, this type of tire could be another great option for consumers.
