On my 2015 GT convertible, around 45000 km I ran into the problem of the front tires (both of them) wearing out on the inside, to the point the cord was showing. I replaced the tires and then went to a specialist alignment shop, which was able to sort of fix the problem. The new tires I put on wore a little better, but you could see it was still happening. I traded the car at 80,000 km for my present 2017 GT convertible.

Last summer I replaced the factory 18" wheels and tires, and then put aftermarket front tires on the '17(mounted on 19x9 wheels) at about 25000 km. IT now has 45,000 km. I was careful to make sure the overall diameter was the same. This weekend I took the car out of storage and as I was checking tire pressures I saw that the same thing is happening, again. I'm gonna take it in and get it re-aligned asap.
To my knowledge neither car ever hit a curb or had any sort of altercation which might affect the alignment.

This is now 2 cars in a row with the same problem.
Annyone else have a similar concern with their '15 and up? Any solutions?
