Current set of rear tires lasted almost as long as the front. I used to get 6 months on average. My main reason for getting it though, was confidence that the rear end wouldn't step in the middle of a turn and end our 18-1/2 year relationship. You'll read a lot of "real drivers don't need TC" crap, but at the end of the day, it's cheap insurance. I don't need it, until I need it.
