I had my last set for 60k miles. I only rotated twice so with an AWD I needed a set of 4 new. Still not bad for messing up and not rotating. The back tires had plenty of tread left. Living in Iowa I've seen all the weather and these tire handled great on ice and snow. I also never had an worries during heavy rain. For the price, about $620 for the set, you can't get a better all around tire. This time I will rotate them to last the duration.
The best tire I've ever owned. After 5 years and 55K miles, tread still looks good. 3 years ago we were trapped on I-70 headed to Colorado for skiing. They closed the highway and we were driving 15 mph behind a line of cars. We watched many AWD's slip off the road while our FWD easily cruised through the heavy snow.
