If you want to compare the tires , read first my topic about it.
comparing tires for replacement
But the overloading is probably the cource.
This can also be for one tire.
so where it always the same tires that blew, or did you have all tires once damaged?
For trailers and 5th wheelers with tandem or tripple axles crossed weightdifferences are more rule then exception.
You have to use pressure needed for the load on the most loaded tire , for all the tires.
To know that weighing is the only way, preferably per wheel(pair), second best axle weighing, but as long as you did not do that , we will have to do with the GAWR's.
You can build in some extra reserve by putting 10 psi higher pressure in the tires then that written on sidewall. Its allowed by TRA for LT and ST tires up to 10 psi, and even 20 psi for truck-tires.
This pressure on sidewall, called maxloadpressure or reference-pressure is not the maximum pressure of the tire, wich is only given on P-tires and XL/reinforce/Extraload.
so give the missing data , and I will produce a picture of my calculator with pressure advice and extra info.
Probably will use the motorhome calculator, if you give seperate wheel-weights.
