That means that the face of the 17x9 et35 wheel is going to be only 1.35 mm (6.35mm - 5mm) off from where the face of the 17x9.5 et40 is on these photos. Assuming the concavity of the 17x9.5 wheel is the same as 17x9, they will look basically identical if you use 245/40 on the 17x9 wheel.

Thanks for the explanation, that makes sense!
