I currently run Michelin LTX MS tires on my RV which I put on in 2013. I've recently had both inner dually tires blow out, on two separate occasions. It's time to replace all the tires. I replaced one of the inner tires with a Michelin Defender LTX M/S and the other inner with a Cooper Discoverer HT3 tire. I wasn't able to get a Michelin so I replaced it with a Cooper.
After somewhat disappointed with Michelin LTX tires on my dually, I went with Coopers. Time will tell if they work out better. So far my best luck has been with Toyo's but I thought I would try the Coopers this go around.
