Tire Help. 19 X 8 Tsw Max Wheels With 1.25 Inch Spacers.

[Emogan]

Hi everyone. I recently just purchased my first mustang, a 2014 GT and am in love. I just managed to pick up a set of TSW Max Wheels from a buddy that are 19 x 8. Additionally he gave me some wheel spacers that are 1.25 inches. I am not very car knowledgeable and am looking for advice on tire size. I live in Ohio so I deal with plenty of rain and some snow. Any advice is appreciated. Thanks
