I know this has been discussed at length many times, but the threads always get so long, and I'm only now in need of tires. This is my 22ft toy hauler. It currently has ST225X75R15's, and I believe the general consensus on here (as I recall) is to move up a size and get LT to get out of the Chinese made tires? If I recall it correctly, what size and any brands to look at and/or avoid?
