Just put a set these on my Infiniti G-37xS last week. Tire Rack shipped them to my Infiniti dealer who did the install. They balanced up beautifully without much weight. Just have about 250 miles on them so far and just tried them in the snow tonight. Pleasantly surprised at how well they did, considering these are not snows, but all-seasons. In terms of wet and dry performance they are very good. In terms of comfort, I'm very pleased as well. Steering response is excellent. And compared to the original stock Dunlops, these are clearly a step up in all categories. I know this is just a quick preliminary review, but it just snowed here in RI. So, if you are thinking of a new set of tires for your G, you wont be disappointed. Michelin's $70.00 rebate, if I get it, helps too.
