Spare tires

We stopped by the Georgetown KY store last week to pick up a spare tire and rim for my parents who were already ahead of us and had struck some debris causing both tires to flatten. To my shock, the service department stated they don't carry rims and tires, they just order them when needed. Are you serious? One of the most needed roadside items and a store that touches I75 does not carry tires? Whats the reason behind this? Went to a much smaller dealer up the road and purchased a tire mounted on a rim and got them back underway.
