Funny you should post this. I was crawling around under my 2017 Sport yesterday and checked wheel well clearance. The fronts are tight, not much room to spare, so the OEM tires are 11 inches wide and 33 inches high (diameter) and Ill stick with them, but there is a good two inches of clearance in the rears on the inner side and about 1 inch of extra space between the edge of the tires and the body. So I might try either 305/50 in the rear or either the 285/55 or 295/60, each of which are 11.7 inches wide. The OEM rims are 20x9 by the way, not sure about the offset.
The 285/55 is 32.3 inches in diameter, just under the 33 inch diameter of stock tires and the 295/60 is 33.9 inches in diameter, or almost an inch taller (or 1/2 inch from rim to tread). Since Im looking for performance and doing 2/4 drop, Ill probably go with a Michellin Defender which is slight less high and is an all season performance tire. But they are big bucks, like $320 each. And to do it right, you should be chipped with ability to edit the tire size of your tires otherwise your odometer and speedometer will not be correctly calibrated. Call a tech at the tire rack, they can help you pick out whatever tire you are looking for. But they wont know the offset or clearance. Good luck.
