1 /5 Diane Lewis: A while back I brought the truck my son drives there to get a new tire. He started having trouble with a tire losing air. He plugged it, it started losing air again and he replugged it. The third time it was losing air somewhere else, he plugged it. He complained he thinks these are cheap tires and we might need a new tire. Thinking this was a different one from the one I bought there I went in and explained the situation. They said they would check it out. They brought it back, gave me the key without saying anything. Then they told me they were able to plug it and charged me $20. 9 hours later its flat!
