Not aware of anyone who is but its kind of on the big side. I'm guessing you'll need at least a 7" wide rim. Its also 8 tenths (.8) of an inch bigger in diameter than a stock 205/50-16 which at 24.1 inches in diameter is what you try to shoot for regardless of the wheel size you may use.
I've been wondering the same thing...since I like my 07 ST 16" wheels I was wondering what tire sizes would fit. I have no idea how wide the stock ST wheel is...I assume 6 - 7" wide. I have the FRPP suspension kit I got from [email protected] so I'm dropped about 1.5"
