http://www.consumerreports.org/cro/news/...wears/index.htm Cliff Notes: - Premier A/S mostly lives up to its claims on maintaining wet traction as the tire wears - Dry Traction on the Premier A/S is a bit deficient compared to the Primacy MXV4, but not by a ton. - Handling, ride, noise and winter weather performance is about equal to the Primacy MXV4 - According to their testing, treadwear is "exceptional" - so I interpret this to mean equal or better than the Primacy MXV4 In addition, TireRack did their own testing of the Premier A/S with the PureContact, Serenity Plus and P7 Plus. TireRack's test results pretty much match Consumer Reports' conclusions. Based on what I am seeing so far, I am not seeing any reason to "fear" the Premier A/S and its shorter starting tread depth. It appears that this tire delivers on the performance promises and the treadwear is appearing is to be a non-issue so far.
