To get a realistic answer you will need to weigh your trailer axles and your tow vehicle .
You did not say but , if your tires are rated for 1820 pounds each on the sidewall that gives you 7280 pounds maximum on your axle weight .
To achieve that weight rating you must be inflated to 45 psi , not more , not less .
Because ST tires are considerably less money than an equivalent pound rated LT tire it is probably wise to maintain a 15 % reserve capacity .
7280 # X 85% = 6188 pounds .
If your axles scale more than 6188 # then you would be best served to check the condition and psi very frequently .
The most efficient way to eliminate tire failure is to upgrade to a tire that has a higher load rating posted on the sidewall , at tire replacement time .
Simultaneously if you can upgrade to an LT graded tire that adds another 10 % of real world reserve .
I made the switch from 1820 # rated ST tires to 2271 # rated LT tires .
But we do more boondock style camping than RV Park outings.
