Tire Works Total Car Care

I'm having a problem with my front end shaking when i'm driving and it shakes even more when I apply the brakes. I went to tire works at 8825 w. Flamingo Rd. Las vegas, NV 89147 and was told that the problem was my brake rotors were bad and the rear shock was bad. I had my mechanic change my shocks and struts and all 4 brake rotors and pads. my truck still continues to shake a little and then alot when I apply the brakes. So last week I went to a shop and had the alignment done and to check the tires to make sure they were balanced, the shop said they had to rebalance the tires because they were not balanced. Since I purchased the tires from your company I have had all my tires rotated every 5000 miles and my oil changed when needed. My mechanic told me that after he changed the brakes etc. the only other possible problem that can cause it to shake is the tires. today I went to Tire Works and talked to Keith Ping the store manager and explained what the problem was and before he even looked at the tires he said it's not the tires and that it's the brake rotors because we must have purchased cheap parts. I did tire repairs etc for 8 years working for Hertz rent a car and I checked the tire depth on all 4 tires before I went to your store and found the depth were from 6mm to 10mm on 1 tire, 9mm, 10mm, 11mm on another tire, and 9mm and 10mm on the other 2 tires. when your manager checked the tread depth he claims ALL 4 tires were at 11. I told him to change the front tires so I could see if the shaking would stop but he refused and said I needed to replace my brake rotors again. I told him to give me my truck and I left. Your Manager thinks he knows more than his customers but with me doing tire work for 8 years and after changing my shocks and rotors and brake pads I know it has to be the tires that is the problem.
