a 215/40-17 should work. I had 215/40-17 Dunlop Direzza Z1* tires on my Fiesta with 17x7 SVT Focus wheels and they only rubbed when I installed the Ford Racing Bilstein autocross coilover kit and had it set too low. The front tires rubbed inside the wheel lining at full lock under heavy braking. They were fine after I raised it up a bit. So... there are 4 tires in that size. Dunlop Direzza ZII. Yokohama AD08/AD08 R and Falken RT-615K.
