Sup guys, what u guys think about the Kumho Ecsta SUper(?) tires? I got them from the tires and wheels package from tries discount.com 1/2 year ago. I was quite satify the wet and dry performance this half yr. However when I experienced the snow for the first morning thsi month, I can barely drive more than 20 miles and I feel a little slip even I braking very gentelly in every stop. Is the performance tires are suppose to be like that or my tires sux?
