Just a logic statement:
Probably the most abused trailer tires are going to be found on 6000# axles. The majority of trailer manufacturers using those axles as OE are fitting them with tires having load capacities of 3420#, 3500# and 3520#. Those tires have a normal life expectancy of 3-5 years even though they may appear like new. That life expectancy will shorten when the tires are abused or not properly maintained. Lots of times the abuse will be unknown to the trailer owner because they don’t have it weighed regularly. That results in overweight conditions for a single tire location or both ends of an axle or all axles being overloaded.
When suffering tire failures of unknown origins, owners like to point fingers at the tire as the sole cause. Right away they want replacements of “better” quality and construction. OOPS! Nothing on the market from other designs qualify as replacements. So what, “I’m going to use them anyway”. The common “so what” tire is rated at 3042#. Under the most favorable conditions that tire only has 42# of load capacity above GAWR. There is no room for any air pressure loss whatsoever. Just a 2 psi drop in cold inflation pressure drops the 3042# tire to 2992# and that’s below the GAWR.
