You can get both 245/35 and 255/35 fronts. For the rear, 275/35 but no 265/35 yet. It is so new, I expect they will expand what sizes are available.
On my OEM rims, I ran 245/35 (f) and 275/35 (r) for my last tires. I plan to run 255/35 (f) and 275/35 (r) on the new wheels coming.
So, although you are right on OEM sizes at present, they have lots of options that will work well on both OEM and after market rims.
