Does anyone know if the Bolt pattern has changed between the '16 and '17 Ecoboost Premium Convertibles? I had a '16 that I purchased new wheels and Blizzak tires for in December and the '16 is no longer with us...RIP...I was wondering if I would still be able to use the wheels and tires on the '17. I did go from the stock 18" tires to a 17" that was thinner to help in the snow. Any help would be appreciated. Thanks!
