That suck but glad your ok and no damage to your truck! As for treadwright they are a great company and as u stated the failure rate is very low. i have seen a few tires come apart in my life and they were not retreads, it can happen to any tire any brand. I love TW and have them on 4 of my vehicles (2 taco's= 285 & 265, t100= 37, 05 ram CTD= 285) they all have been great with no issues, The 37 get down right abused and they are holding up great. let us know what they tell you about the tire.
