Look what happened to mine , I have 19,000 kms on them . Had a vibration coming from the front of the car the other week , we couldn't find what the noise was but it sounded like it was coming from somewhere around the rad . So , we thought we would lift the car , take of the skidplate and check from underneath . When I jacked the front of the car , I saw the inner sides of the front tires . WOW , I just about crapped my pants . Needless to say , I had to replace both front tires . Of course , as is usual , cant get the run flats due to short supply , so went with Pilot Super sport in Non run flat , slightly wider tire at 295/30/19 . Got the front end re aligned due to aggressive settings from factory .
