I bought some used tires once. Had them put on an old truck that I drove maybe once a month. No use in buying new tires for a truck that I only put a few thousand miles on in the 6 years I owned it. I did want tires on it that is safe to put on the road.
I have known some people in the past that bought new cars, took them to a tire dealer and had other new tires put on them. Those tires had less than
100 miles on them.
