Tire Sidewall problems of the 2004 Chevrolet Silverado 1500

I am filing this complaint about greendiamond tires of NY. I worked there 2 1/2 years and was let go because I spoke out about the poor quality of the tires being built. There have been numerous tires that have had catastrophic failures,resulting in the company covering them up by paying for damages done to vehicles. I have in my possession several tires with these defects. I told management about the numerous problems with the tires and my position at the company was eliminated. They continue to sell and ship these tires with no concern for consumer safety,even after they themselves checked and gauged these tires only to find the sidewalls,top rubber and casings used in the build process to be faulty. Please investigate this company before someone has a fatality driving on these tires. I myself had a tire explode on a company truck on the highway and was barely able to control the vehicle.
