Tire choice Did work that was not authorized. Tampa Florida

We took our car to Tire Choice of New Tampa, Florida. The front tires were shaking. They stated it was the inner tire rods. They suggested that we replace the front tires. We stated that we couldn't afford tires and just replace the tire rods. The quote was for $450 which seemed a little high. When we picked up the car, they had installed 2 tires that I had never heard of. We spoke to the manager and all he could say was that we told them to replace the tires. if I were to replace the tires, I would have researched and then discussed what tires they had available. We weren't given a choice.
