I just wanted to share some information about my recent tire blow out. these tires were the original tires on our 'O6 Hurricane. The DOT date on the tire was 3305 meaning they were manufactured in the 33 week of '05. I never had a problem with any of the tires until this blow out in September of 2017. These tires lasted 12 years. I do store the motorhome out doors but since we purchased it in 2010, We've kept tire covers on while in storage. There were about 27,000 miles on these tires.
Looking closely at this tire after the blow out, I think I can actually see what happened and why the tire gave way (other than its age). I believe that throughout their life, I did run them under-inflated too much, Wearing the outsides of the tires.
Notice in this first picture that you can still see siping on one side of the tire (top side in the picture):
The second picture shows the other side of the tire where not only is there no siping but there are actually stress cracks in the tire from being under-inflated:
The third picture shows where I think the blow out began. The tear looks to have started at the stress cracks?
After a little research, I decided to replace all 6 tires with 6 more Goodyear G670's even though they are expensive. I chose these tires for 3 reasons. 1) they have an additive that makes the tire last longer than a regular tire specifically for an RV application where it gets stored most of the time. 2) Most other tires of this size are truck tires and are designed for a higher air pressure (110 PSI) making the ride rougher. 3) They are made in America.
I was able to get the 6 tires from simpletire.com for just under $2700 shipped. Warning: most tire shops can't balance these tires.
New edit:
I want to make it clear that I am far from an expert in this matter but I feel like I learned something in this experience that I wanted to pass along to others. I thought that the life expectancy of most tires was 10 years and that since i had them covered with tire covers i could squeeze out another year or two. I knew that they needed to be changed out soon but honestly, the tires still looked great at a glance. However, I should have looked closer at all the tires before the blow out. This was the only tire of the 6 that had stress/heat cracking on it. And yes, These tires are prone to "rivering" Where the outsides of the tire wear faster than the insides. Its hard to notice. You have to pay attention to the siping on the outsides of the tire. If it goes away, the tire is getting worn.
In no way am I trying to give the G670 tire a "glowing review" because mine lasted 12 years as someone posted, but I think its very relevant to this case and it is interesting. I mean, if you look at the other five tires, and they looked pretty **** good! no sidewall cracking and still lots of tread. That said, I will never go a day over 10 years on any tires on our motorhome ever again. Less than that if they are cheaper tires.

I sure hope this post was meant to be a GLOWING review of the Goodyear tire. 12 years old and still going? That's completely awesome since the average life expectancy of an RV tire is about 7 year. The fact that you were willing to put your life on the line driving on 12 year old tires is a whole different topic.
Glad to hear you are OK and it sounds like replacing them with another set of Goodyear's was also a good choice.
