Energy Saver A/S 68T impressions

43.987. A/C or heat almost always on. Tire wear is still excellent. A little twitchy probably because of high tire pressures. Handling trade-offs from overinflation expected. Twitchiness keeps you on your toes in crosswinds! Still overall happy with them.

 

42.00. A/c on all the time. At this point, I think I can safely say that the E/S are superior in all ways. The drop in noise is significant. The bump in fuel economy is marginal but noticeable at about 5%. The handling is improved, but I think most people will not notice it.
Good tire. Highly recommended.

 

45.9. a/c usually on.
