My holiday drive proved to be the best test of these tires. Drove from Minnesota to Chicago (at good clip) with no issue. Noise level was tolerable, but depended on the road surface and not so much the tire.
While in Chicago, there was a snow sleet mix that dropped 4-6 of the mess. This proved to be the best test of the tires, and passed according to my driving style.
I was running 70 Lbs. (sand tube) of ballast in the trunk, and my car felt loose in the rear-end in turns, but I don't feel that it was the tire that was losing traction it was question of weight distribution. Not to mention that I was pushing the envelope for...testing purposes.
At stoplights and long stretches of this particular matter the tire's would grab really well, despite my lack of ballast.
One word of advice for the transition of tire's though. These tires have a rubber-band feel when the daily high temp is above 44ËF, you will notice some sway.
In summation: I would recommend these tires for people who have a Panther, and can only imagine how well they work with smaller cars.
When it comes to the integrity of the tire? There is a person at work that ran these tire for an entire year, and showed minimal amounts of wear, cracking, breakage despite being used in warmer temperatures.
