Yeah, for reference, I run 255/40-17 on 17x9 ET41 wheels. I think you should be fine on clearance as long as you're not running a 50+mm offset. The awd wagons shouldn't have the fuel filler issue that fwd cars have.
You should be fine on the inside, may have a little poke though. Have you done the fender screw mod? You can google it, it's a five minute job you don't need to lift the car either.They are 18x8.5 +29 offset
