But you should know that all-season tires, by their very nature, don’t deliver optimum performance in any season. To be pliable in winter, they’ll give up handling in summer. To work well in rain, they’ll give up grip in snow. True, you can get all-season tires with the M+S symbol signaling mud and snow usage, but it’s just snow. Not ice, not sleet, All-seasons will never come close to a dedicated winter – or summer – tire. A little less performance on a warm, sunny day may be a drag, but it won’t put you in a snowbank the way a lack of performance in winter can. Just a little something to think about next time you’re shopping tires.
