Sailun S637 or Goodyear G614

I bought 17.5" rims and Sumitomo tires last year for $550 each mounted, balanced and delivered. I wanted to get the G614 but it was close to $400 mounted and every thread I read on the G614 never got past page two without someone posting that when the tire blew Goodyear would pay for damages. I have a $50 deductable on my trailer so that wasn't what I wanted. I was lucky when my tires blew they just took out the fenderwell and some trim and I could still use the trailer but I couldn't drive in the rain because the water would go in the trailer so it was a pain. Then I had to leave my trailer at a repair shop and it is never the same as the original. I made up my mind that I wanted the best tire I could get so I didn't have to go through that again. I guess I paid $600 for that peace of mind and haven't regreted it. I read about the Sailun, the redesigned G614 and the redesigned Carlisle RH but I will let someone else test these.
