Something else that I learned, was that ST trailer tires (e.g. ST205/75R15) are only rated for 62 mph max sustained speed. Yet I see thousands of guys pulling campers, race cars, boats, etc down the highway at 80+ for hours on end usually with ST trailer tires. And all of the ST's are dirt cheap, Korean or chinese garbage. Even the old Goodyear Marathons-which were considered "good" aren't as good as they used to be, but I'm told that GY has now started building them again here in the USA due to demand. Good. I might try a set next time I put tires on the race trailer. Or maybe just go with 16" and use LT's if they'll fit.
