Yokohama g-91 tires- on a subrau forrester 225-60-17 with less than 30k miles the tires were balding. rotations were down between 6000 and 7000 miles- like clockwork. i wrote yokohama. i have not received a response. i have spoken with other owners, (subrau using g91) and they have noticed this problem,too. i have purchased another brand of tire as these are dangerous-
