I'm done with E rated tires. Where I used to work we bought 3 Dodge 4x4 with Cummins diesels when they first came out. They all came with E rated Michelin all terrains. We had 14 tires total(2 trucks with spares. Out of those 14 tires, 7 blew out from belt shift with less than 10,000 miles on them. We had 500 gallon tanks on 2 of them which equates to over 5000 lbs in liquid alone. The other truck was just a transport truck and 3 of the tires blew on that one too. It never had more than 400 lbs in the bed.
I told the owner that I refused to drive any of the trucks till we get rid of them and they agreed. Now you have to remember They had been running different trucks for 20 years and NEVER had one blow and they ran EVERY cheap tire you can imagine. Again, they NEVER had one blow, even running them to the cord showing.
I thought maybe it was an isolated Michelin this but earlier this year I had this happen on my long distance truck.
Tire was a Goodyear Wrangler E rated tire. They came on the truck and had about 3/4 tread on it. I've never overloaded this truck. Truck was empty and was going about 60MPH when I heard what sounded like a rock caught in the tread. I started to slow down and it started shaking and hit the brakes a little harder. Then all heck broke loose. This all took place in less than 10 seconds. Tire NEVER lost air, the tread just broke free from the case and slapped the backside of the bed.
From my real world experience E rated tires are "over rated" and I'll never buy any again. Good luck if you decide to try them.
