I got 4 tires replaced on my car but I only needed 2. The two good tires I told the technician and the manager to put the two good tires that I had in my trunk. I get there to pick the car up and they told me the tires was in my trunk. I looked there but there were no tires. I go back and ask him about it and he said they're in a pile of junk tires. I said well can you have someone to get them. He said sure, he goes back there cannot find my tires... Comes back and tells me I'm sorry there's nothing I can do .I said you have stolen.. I told him I would like to be a reimbursed for my tires and he said he can not do that.. He told me sorry you going have to take that as a lost... The address is 2304 Bearss Avenue Tampa FL 33613. I do not recommend anybody going there. I believe they sell your used tires to the used tire shop. That's why they did not give me my tires back.
