Well I had one of my Goodyear Marathons seperate on me Tuesday evening when coming home from fishing. I just happened to look in my mirror and noticed a big bulge in the tire. Luckily I was able to limp home with it instead of having to change a flat on the road. And when I say LUCKILY, I mean it... one of the lugs was cross threaded and I liked to of never got the dang thing off using my 4-way that I had at the house. I would of never been able to get the thing off if I would of had to of changed it with the factory tire tool in my truck (4-way is now in my tool box). This wheel had never been taken off the trailer since I bought it 2 years ago, so it had to of been cross threaded at the factory. So it might be a good idea to take a few minutes and make sure none of your lugs are crossed before you get out somewhere and have a flat!
Also, on a side note, does anyone know if we have a road hazzard on our tires?
