My trailer had 15 in ST tires . I bought it used . The first thing I did was buy 16 in steel wheels , LT tires , and the screw in valve stems . Why ? Mt trailer is a 10K lbs maximum weight . My tires combined have a capacity of a bit over 12K lbs . I have plenty of reserve . Speed , the tires are rated for 95 mph . Dont plan on towing that fast but I have plenty of reserve .
I have construction trailers , tow behind air compressors , utility trailers . I have had enough tread seperations with ST tires . The only trailer I have with ST tires is my " go to the landfill trailer " I am using up what ever ST tires I have left .
Read the discussions on this forum , boat forums , horse showing forums etc . Make the decision thats best for you .
