The ONLY reason I talked about Sailun tires and mentioned the 16" is because the OP was specific about what tire they wanted.. I agree with JIM, but again, OP was specific about a particular tire.. Seems to want to go up a size.. 16" XPS ribs would work and quite a few more for that matter... if only going to 16", nothing wrong with running your trailer on tires with a great reputation, as well as being reliable.. peace of mind is hard to put a price on.
