We just bought a set of Toyo Open Country T/A tires for my wife's 04 Trailblazer 4x4. Anyone run these tires for anytime, I read some reviews and they seemed all over the place some people got 50,000 + miles while others said they where wore out in 20,000 miles, most agreed they performed well. I found these surveys with some saying they lost up to 2-3 MPG with these tires. Is there any of you with any experience with these tires. Thanks
