Tire decision... My turn :)

Tires for the 7k axles were the most confusing thing on my trailer. I had Towmax load range E originally (not good) and replaced them with Carlisle load range F (worse with 2 blowouts at 3 years). I spent more hours online researching tires than anything else until I finally threw my hands in the air and went with 17.5" rims and load range H Sumitomo tires. Overkill for sure but the only other option I could see 2 or 3 years ago was the G614 and it's claim to fame was "Goodyear will pay for damages when it blows". I have insurance to pay and just wanted to be on the road not on the side of the road.
