The common trailer tire sizes come in and go out of our warehouse so quickly that nothing is more than 2 years old. There are a lot of larger trailers that use 235/85-16 tires so I do consider that a common size. In that size and load range G we have 2 options: # TTWPRG235R16 and # LHWL410. Both are rated for 4,400 pounds at 110 psi. The Westlake tire # LHWL410 has a 5-year warranty which is longer than others at 2 years.

The age of a trailer tire is only a concern if it was not properly stored. That is to say that if kept out of the elements and stored inside there is nothing to worry about with that age. Our manufacturers and us store our tires inside out of the elements so they won't suffer damage from the sun or any dry rot. It is difficult to find trailer tires that have a date code less than 6 months old because from the time they start making them to the time they arrive on shelves is at least 6 months.

A lot of the time trailer tire failure is attributed to the tire construction or that it was too old for use. But 9 times out of 10 a trailer tire fails because it overheated. And out of those another 9 times out of 10 it overheated because it was under inflated. Trailer tires should be inflated to the max psi indicated on the tire.
