On my 15 GT the front tires(265/35/20) wore out alarmingly on the insides. At around 55000 km both tires had exposed cords and had to be replaced. I don't k now where this came from as I have no recollection of hitting anything.

Now, I have a '17 GT with 235/50/18 tires and today I happened to notice that the inside edges appear to be wearing very quickly. It's quite noticeable.
I did not seem to have this problem with my '12 or my '14.

does anyone else have this problem? Is it endemic to the S550 chassis? Or is something wrong? I'm about to install 19x9 front wheels with new 255/40/19 Continental tires, and I don't want them wearing too fast.
