Perhaps I'm being too picky with this thinking, but I don't know how much the tire sizing factors into how the car sensors control things. With the stock sizing having the front tire diameter .3" larger than the rear, I wonder if using a 35 series front might be more in line with the stock sizing? Probably won't affect anything, but it would be frustrating if the car thought the rear tires were spinning in relation to the front since they are rotating faster than normal in comparison. This car is so computer controlled with its various modes, I wonder if a basic such as tire diameter is now dictated to us?
