Hankook RS3's recently changed their treadwear rating from 140 to 200 in order to meet with the compliance of the street class change in 2015. Question is, Did their compound actually change or did they just decide to stamp a new treadwear rating on the side? Any input on this? Since the rule for the 200 TW doesnt go into effect until 2015, I may pick up a set of 140 TW for the '13-'14 season. For the 285/35R18 RS3's, tire rack even has them listed twice. One for 140 and one for 200.
