putting 17" wheels on a boat trailer. My son-in-law has a 2020 Vexus VX21, and about a week ago hit something on the interstate and bent one axle on the trailer. He ended up having a blowout on the right front Kenda Loadmaster tire and destroying the rear tire, fender, etc (not the fault of the tires). While shopping for a couple of new tires, or maybe a full set, we have discovered that we could not find any of the major manufacturers that build a trailer tire in ST 21565R17, and all the rest are China Poppers. I understand that Ranger and possibly other manufacturers put 17's on their trailers also. I've read where some people have gone to Michelin passenger / small SUV tires in this size on their boat trailers, but I've always been leery of using LT or passenger tires on my trailers. I have a friend who is the manager at one of the Discount Tire stores, and the only trailer tire he could find in that size, that they can order, is a Vision Heavy Hauler, 10 ply rated, Load Range E. He thought they were built in South America, but guess what, after checking - another China built tire.
It seems to me that a 16" wheel would give us boaters a lot more choices for tires. Any thoughts on this issue, and suggestions on the best way to go?
