My 2012 Mustang V6 is equipped with 235/50/18 all season tires. I was sure that installing a narrower 225/60/17 and higher profile snow tire would result in the typically squirmy and soft performance which many poorly constructed snow tires are afflicted with. I can confirm what several reviewers have claimed about dry performance, and after a few days of spirited city/highway driving, I am amazed that I can barely tell the difference from my higher performance Pirelli Pzero All seasons, and the xi3 tires.
I will be in no rush for winter to end as I've been in the past. Will update once I test in the snow. I considered higher performance snows such as the Aline series but I'm glad that I've gone this route, knowing I have a tire that can actually handle snowy/icy conditions. I have no experience with the Alpines, but the common criticism is that they do not perform much better than stand all season tires in bad conditions. That is a deal breaker for this beaver loving Canuck!
If you drive a sport coupe and are worried about driving in dry conditions, don't be. Similarly if you get some snow during the winter, consider passing on the tires marketed as performance, and get a tire which can keep you safe!
I purchased the xi3 tires with the Elbrus I02 silver painted wheels and they look really great!
