Just wanted to see what interest was out there - I have a set of OEM 17" wheels for the GTO with 225/50/17 Blizzak WS50’s. Have seen three winters, but a decent amount of tread left (probably 2 more seasons).
Wheels themselves are slightly curbed, but otherwise in decent shape. Wheels are 5x120, 17x8".
Will hopefully post more detailed pics shortly.
