Camber-wise,I could go further with some GC Street or Dinan camber plates, not sure if it's worth the cost / install / tire wear for a DD.
According to Tirerack the measured rim width for 255/40 17 is 9. The range is 8.5-10. So the optimal rim width would be 9-9.5 for this tire.

For street driving you will not notice a huge difference between 255 and 245.
