More tire porn! I went ahead and picked up a single set of the 285/645-R18 GT-O's from Hoosier/Conti. Can't beat $110/tire for sticker slicks!
They're a little taller than the 265/645-R18 Wets, but appear to be exactly the same width unmounted. Go figure, but works out good for me
I probably won't mount these until my RS3's die sometime in the mid-late summer.
