First let me say I feel obligated to write this review as I always read others reviews to help me in my decision as to which tires to buy. I had decided on a particular tire for my car but was concerned about giving up performance that is the usual trade-off when buying a snow tire. Thank you to the Tire Rack representative on the phone when I called to obtain more info. He asked good questions and when he found out I had a Porsche, recommended a tire designed specifically for my high performance vehicle. Now as for the tires, I paid what I expected to for a lesser, non high performance snow tire. I drove in Oregon in late December during serious snow and ice condidtions. The tires never slid, stumbled or had any trouble with traction on roads consisting of snow, ice and a mixture of both. The tires are as quiet if not more so than my stock summer tires which was a major surprise. I was willing to sacrifice comfort and noise for the security of a dedicated snow tire. On dry roads they ride, handle and brake excellently. and in the snow, I was so grateful I did not settle for just all season tires. I have no doubt in my mind that all season tires would not have been able to handle the conditions I drove though. The peace of mind these tires gave me and my family cannot be overstated. The added bonus that Tire Rack had them for the same price as all seasons was an added surprise. These are the third set of Michelin tires I have put on three different vehicles and I completly understand where the extra money goes. They may cost a bit more, but perform better, last longer and ultimeately will save money over other lesser brands that have an inferior warranty and performance. Back to these tires, I trust them enough that I would have no problem recommending them to anyone who wants the security and peace of mind they afford them and their family. I cannot say enough good things about them. Well done Michelin, your engineering expertise is unsurpassed!
