Fixin to buy Sailun S637s

[Ford350man]

Need some advice from fellow Monty owners. When I acquired my 2006 3475RLS in 2015, the dealer put new 235x80R16 Transporter tires on it. No doubt they were China bombs. Had a blow out a year ago with minimal damage to the trailer fortunately. My local tire dealer talked me into a set of Trailer Kings. Didn’t do enough home work when I bought them. Only, 3000 miles later I was losing air and found two small bubbles on inside of the tire before leaving on a 1000 mile trip. Dealer replaced it without cost so far. I lost all confidence I had in them. After readin all the posts from ya’ll, Sailuns seem to be the recommended tire(even though China made). The small print on these 235x80R16s (4,080 lbs at 110psi) recomends high pressure wheels. Here is my question- Are my current wheels adequate based on the following or do I buy new wheels also? Trailer GVW is 14,000. Two 6000 lb axles. Hitch weight is 2435. Total weight on axles of trailer is 10,540. Actual weight on left front trailer tire is 2900. Weight on the other three tires is a lesser amount. My wheels are 3750 lbs max rated. Can I safely install the Sailuns on these wheels at 110 psi. I am definitely under loaded. Any suggestions?
