they are very soft & i would not drive faster than 75-80 with them, but they are totally awsome in the ice & snow. they saved me once. i hit a patch of ice on pa interstate 80 @ 65mph. i could feel the car slide, but i was able to control it. i would have spun out with a standard tire. they only need to save you once to be worth the $418.00. i just keep in mind it's winter time, not a good time of year to drive enthusiastically.
thanks
