I bought BF Goodrich Traction T/A's (H-rating) last month. today, it's snowing. the ground only had like 1/2" of snow. i was going about 30mph in a 45mph zone, and left plenty of space between me and the car in front. he hit his brakes, and i hit mine softly since there was lots of space. i noticed i wasnt slowing down as normal. so i pressed on the brakes harder (not ABS), and my car started to turn sideways about 10 degrees. Traction T/A's have AA traction rating. Is it normal for new tires with a good traction rating to slip and slide when braking in light snow? If so, WHY?
