I just got the cs5 ultra touring. I don't know if there is a difference but I like the tires so far. Only 2 thousand miles on them but very quiet and nice ride. of course anything is nice compared to the oem,s that were on it. Nice tires. I think you will be pleased.Just bought for install on the 18th 4 new tires, Cooper CS5 grand touring tires in 225/60/16, will report back on how i feel about them, will try them out in some sugar sand near me in south jersey.
