Yesterday I took the plunge and got 4 new snow tires for my '14 GT Premium. The owner of the tire store told me I really didn't need them as my Mustang has all season tires, but I feel much more secure, here in a suburb of NYC, with snow tires on my car. (Remember last winter?) Anyway, one of the workers there was helping me put the tires they took off into my SUV and told me, "These are really good tires." He then proceeded to show me how the sidewall is hard too flex and told me if he did that (grabbed the sidewall and pulled) to other brands they sell, the sidewalls would have flexed with ease. I think in getting the snow tires I have now arranged for a very mild winter ;0)
