We have Rainiers G rated on ours. Have about 3300 miles or so on them and haven't had any trouble yet. I contacted Keystone regarding the tires last year when we bought our camper and they said they are made at the same factory as the Sailuns and they interchange them with Sailuns on their campers- it just depends on what factory has more of in stock. They said they hadn't had issues with the Rainiers like some of the others. That being said..we watch them closely, make sure that the tire pressure is correct before we pull our of home or campsite. We plan on using them again this (2nd) year and then will probably replace with Sailuns next year. However if something happens this year to any of them, we will replace them all. We have been told that once one tire blows that it puts stress on the others (no matter what brand)
