Blowout on Goodyear G670

July 8, 2017 I was traveling to Dallas to Rangers game on I-20 in '08 American Eagle motorhome. I had just got on I-20 from Toll 49 when left front steering tire blew out. I had just passed a truck and was in left lane( probably going 70 mph)when it blew. Pulled me into median.It was all I could do to try to keep it from going straight left. How it didn't turn over, I don't know, was in there 400-500 yards before I could get it under control and eased back on Interstate and crossed over to Hwy 110 exit and parked in front of a convenience store until I could receive help. Eventually got another tire from Goodyear Commercial Service Center. Upon returning to home, app 50 miles, I took it to the body shop to have damage repaired. The owner said this was the third Goodyear G670 tire he had seen blowout in last month. I live in small town of less than 14,000 population. My tires were put on new in October, 2013. The other two guys tires were 6-7 years old. The tire Goodyear put on was a 2015 tire. Didn't see that until I got back. They would not exchange it. The tires on coach were 3 years 9 months old with 17,000 miles on them. They are supposed to have a 5 year warranty. I will be replacing all tires(including the $1180 new replacement) with Michelins. Has anyone had similar experience?

I've had two blowouts in an RV (tag and inside dually), both were with GY 670's, 6 and 5yrs old respectively and both in NY. Having said that, I'd first blame it on NY, before GY and with all the road hazards on the thruways. Especially since I keep them aired up and then some. Having said that, I'm convinced that no other tire, including Michelin would guarantee better results and also that no Chinese tire would do any worse.
History and care are important with any tire, but with these two instances, I personally cared for the first since new and with the second, there were two previous owners, right before we purchased, so.......
As for the 75mph speed limit on these tires, for me to even approach that, is mind boggling, so doing 70 in a motor coach is out of the question for us and reserve that kind of speed for our cars, if even then. In the old days, trucks and buses were limited to 60 and when they had it right and most sure the braking and handling still isn't on par with a sports car. I also believe that the truck speed limits are a result of lobbying and it's still all about money, despite what concerns the government might have for safety.
