i have the 712's on my 17'2 and the ASX's on my 15's which i am driving right now. They r both good tires. i liked the 712's because of its better grip, but they r summer tires. The ASX's have about 10K on them right now and they r still great in grip, but a bit louder than in the beginning. But since u live in Canada, i would say to go with the ASX's for its All-Season capabilities.
