I have two sets of the Cooper AT3's and love them. Went to the Cooper website cause I heard that they were introducing an updated version. Turns out there are several. The AT3 remains, the AT3 LT, plus a new AT3 XLT, a AT3 4S.. The Cooper website doesn't give much info except a description. Not much info on the net yet because they were introduced this weekend. I did find a brief article at www.moderntiredealer.com. Look under news.
