I just rotated my Comfortreads today and measured tread depth. Fronts had 73% of original tread, very even wear, no cupping.:thumbs_u: The rears, however, only 36% of original tread. I would guess in the hands of a normal driver they will go 60-70K. As good as they wear and ride, I probably go with a higher performance tire next time. I had traction control engage at 65 mph as I pulled out and passed a car on a slightly damp road. Wet traction a little suspicious.
