I own a 2013 Open Range and can tell you for a fact that the stock tires OR put on these rigs are trash! Do your family and all the other drivers on the road and immediately put new tires on that trailer. My stock tires lasted only a year and a half (12,000 miles) and 3 of the 4 separated on one trip. Luckily I had TPMS that saved us and I was able to get to a tire store immediately off the freeway. Many phone calls later to OR and I was told that they put the cheapest tires they can get away with, no matter how many buyers experience blow outs! Good luck.
