This is my first question here, and so if this question belongs somewhere else, please let me know.
In July, I got a flat and bought a new tire. The tire cost just over 100 dollars (including the labor). It has no hubcap. I haven't really thought about it, but this week the tire pressure light went on in my car and it was only that tire that needed air. It is the rear driver side tire. Is this a sign that the tire was bought used? The auto shop where I bought the tire (an established chain) did not mention anything about it being used.
In addition, the shop did not replace the spare where it belongs under the car after putting in the new tire. Is this a reasonable complaint?
