I have 18.5x8.5x8” on my single snowmobile trailer. C rated Carlisle trailer tires with max pressure at 50psi but I run at 40 cause the weight is not there on the trailer. It’s usually just an ATV or a sled on it. On occasions I haul a boat on it too above the ATV.
Again, 60 mph has never been an issue.
