I have a 2015 C7 with the Z51 option. Does anyone know the width of the wheels of the 19" fronts and the 20" rears?

I want to put wider tires on the car and am trying to decide how wide I can go without replacing the wheels. Thanks for your input.

19 x 8.5 front - widest would be a 255 - 265
20 x 10 rear - widest would be 305

I have 255/35/19 in front and 305/30/20 rear - no rubbing. 305 is about as wide as you want to go in rear on stock wheel.

You would be best leaving the stock rubber on the wheels and picking up aftermarket wheels if you want proper offsets with wider tires - do a search for wheel sizes, lots of info here
