235/55R 18 I took my car for a tire rotation at a tire shop. I was told that the right front tire was not good so I asked to be replace with another new tire I had, which was exactly the same Yokohama tire my car had on. When I drove off the shop the tire started making a weird loud noise so I drove back to the shop. They switch the tire to the rear and there I noticed that was a different tire, not the new tire I have provided them. I asked the guys where my tire was and why they had switched it with an old-use worn tire. They denied doing so and refused to give me back my tire. Besides putting a used-worn out tire, the tire also has a different speed rate than the rest of my tires. Since it is raining in Houston and having different speed tires is itself dangerous, I found this improper and in disregard of putting my safety in danger. My tire was a Yokohama Brand; The shop switched it to a worn-used Dimax brand with a different speed.
