Thought it appropriate to write a review after managing through Snowmageddon in Atlanta on January 28, 2014. These tires are about 2 months old and replaced Yokohama Avid ENVigor's that were on the car when I bought it used about 15 months ago. To say these Primacy's are an upgrade over the Yokohama's is an understatement. The Yokohama's are VERY noisy, and had modest dry traction--especially cornering--and even worse wet traction, despite an aggressive tread pattern. The Michelin's are very quiet, comfortable sneakers for my G37S are even are more than admirable through spirited take-offs and cornering on wet and dry pavement here in the ATL. However, when challenged with our great snow/ice event this week, showed their vulnerabilities. Snow traction was fairly good (we only got 2), but on the icy conditions beneath the snow, they were horrible. I managed to keep it out of ditches and off of bumpers and made it home unscathed, but without my northern, snow-driving capabilities (from PA), not sure I would have pulled it off (in a high-torque, rear-wheel drive, staggered fitment) without them! Love my Michelin's 363 days a year. But any more frozen stuff here in the ATL, and I'm not sure they would be the choice. So, if you are reading this from anywhere above the Mason-Dixon, you may want to think differently!
