Hankook optimo 725 p205/55r16 tires sidewall with extreme cracking! very similar to the hankook dynapro recall. cobalt has very low mileage, so many consumers may not be experiencing a problem of this sort due to a car with higher mileage (and needing a tire change). i have contacted hankook and my new car dealer (kenny ross chevrolet), but has promised me nothing to this point. i am terrified of a blow-out, and possible bodily injury, due to the extent of the cracking sidewalls. also, these tires are leaking air pressure, which is a big concern that it may well be the valve stem, or possibly the cracking of the sidewalls. all four tires are cracked extensively. *tr
