I drive pretty easy on these tires, yet my rears have lasted less than 10k miles. Is that normal? My alignment is dead on. I drive 50/50 city/highway. Our streets around town are in pretty rough shape. Could that have anything to do with it? Or is this normal for the F1 GSD3?

Also, could anyone suggest another tire for the rear (my F1s on the front are quite new)? I've tried Fuzion ZRis and they last almost 20k and are nearly half the price, but of course aren't as sharp as the GSD3. I may be going back to ZRis unless someone can recommend something different. I don't mind paying ~$150 ea for a nice handling tire, but not if I can't get 10k miles out of it.

 

10k is about what i've gotten from every set of rear tires i've ever run.
140, 180, 220, 260, 300...doesn't seem to matter lol

10k is about right. plenty of people get more, plenty of people get less.

 

I would say that is not unheard of on the S2K. Check the alignment and run less toe in on the rear and the tires shouls last longer.
If I can help with the tires let me know.
