Douglas Tires review: Poor quality, failing tires, worn out tread fast

I have a 1998 Plymouth Breeze which is my everyday driver car where i go to college, work and family. I have installed 4 of these tires on two vehicles and all tires are wearing out at 7, 000 miles and developing bubbles in the tires and blowing on the sidewall. Rubber is soo thin that any hard objects on the road can easily puncture these tires, had a chicken bone, a rock and metal cans cut through this tires. Only two months and the tire has failed how terrible. Going to buy me Kumho tires which are a couple dollars more and last 75, 000 miles. I guess you get what you pay for.
