Comm 2's both worn out at 18000?? plenty of rubber left but i had steel showing and a very slick rear before coming close to wear bars. Switched back to dunlop this set, last dunlops got over 25000 both tires with lots of time left.
Tried the comm 2's wont be going back. Had severe cupping on front and the rear was very slippery on the wet. deadly the last couple thousand miles.Was told it was caused by spinning (burnouts). Well i thought it was my clutch going, I could spin the tire through 4 th gear.

 

I think the bigger ones from the 09 and newer last longer. Mine cupped real bad.

 

I've gone back and forth between E3s and CIIs on both my 02 RKC and 07 EGC. New tires are always better.. For me mileage was the same.. I've been trying some E4s on the rears and am liking them but only have a few K on them..
