With a rolled guard lip and correctly centred rim offset you will get 265/50/14 under the rear as low as you like. Get the offset wrong and fail to roll the guard lip and it will scrape.
A 265 should really be on a 9"+ rim. If you are going low 225/60/14 would be the best match for the 265/50/14 rears for steering and ride comfort.
