Mike you need to look a little further, both Steve Huber and I have had G670's explode, I kept our coach from hitting anything Steve wasn't as lucky. I also had a Goodyear tag axle G670 explode just down the road from out house here in Wickenburg. These tire were only 5 years old, no sign of sidewall damage and inflated properly. I will not run a GY tire on anything I own. Had the same problems with their tires with my trucks.
