We're talking GT350's, not regular Mustang GT's. Those tires don't even come close enough in size for a GT350.I've had a couple of storms with this Mustang. I recommend Michelin Cross Climate 2 tires. Not the cheapest but okay in the dry and surprisingly good in the snow. Almost as good as any dedicated winter tire I've driven with. I'm out accelerating every 2WD car, and don't forget, AWD doesn't help a damn with turning or stopping.
So why put away your Mustang? It's still a track star, just buy it some snow boots. Sometimes it's even more fun because you can slide the car intentionally without having to speed all the time.
Found this review. Good channel BTW:.
