You'll spot rubbing on the fronts by running your fingers round the front of arch behind where the bumper meets the wing. If it is rubbing you will gradually get a flat spot at the top of the liner on the edge where it bends inwards from the strip securing it to the bumper. On the rears just feel around the front and back of the arch at the top for a similar flat spot. If you get any rubbing I'd put money on it showing on the front drivers side first, but tbh with 12mm spacers you'll probably be ok. Tyres with less rim protection rub less as well I think.
Driving the car normally you shouldn't get any, except on really really bad roads. You'll be able to tell if it's rubbing when driving it it hard - particularly on roller coaster roads like the one up to Glenshee we did, or on left hand corners - because you'll hear it. It used to make me cringe every time I heard it, now I just mentally stick my fingers in my ears and go 'lalalalalalalalala' in my head
