walmart just repaired tire for me. now when i drive the car there is a loud thumping sound. what could cause this?
my tire had a slow leak, i took it to walmart to be repaired. it was fine when i took it there. after the tire was repaired i drove down the parking lot and heard a loud thumping noise that was not there when i took it in. walmart says they don't know what it is. anyone have any ideas?
