The reason why mileage on trailer tires does not matter

You can read through the .pdf, but here are the Cliff Notes:

Tire manufacturers add waxes and paraffins to tire rubber for protection against ozone (leading cause of rubber degradation). As the tire is used, the heat and flex migrates the wax/paraffin to the exterior of the tire, ensuring a constant supply. When tires are in a stationary state, these materials do not get migrated to the exterior, resulting in more ozone damage than would be seen on a tire that was being regularly operated.

That is why you check manufacture date on tires when purchasing. Also why a trailer tire that “looks” good can be a ticking time bomb. Just because you only pulled your trailer 1,000 miles in the last ten years does not mean your tires are still good.

Just a PSA...

Great information and so so true. I was "that guy" many years ago. I purchased a boat that had "new tires" by tread appearance. I looked at the tires a handful of times before heading home, and when I asked about them "they were new before the boat sat for a handful of years." I told my wife we will be lucky to make it home on those tires. 110% I didn't make it 10 miles down the road before one started to separate and blew. The second one did the same thing as I was coming down my road.

I treat tires like they have a shelf life, once reached regardless of remaining tread, they're getting replaced.

Only supposed to leave trailer tires on 4 years I stretch it to 6

I usually stretch it to failure

Do any of the tire care products serve as this protection.

I doubt it but the pieces are shiny.

Found this out the hard way - bought a boat (very lightly used) that likely had the original
tires (15+ yrs.) and thought I would 'limp' home (tire and tread looked great).
First tire lasted 60 miles, second one another 80 miles. Looks can be deceiving ...

Those cheap azz Goodyear Marathons ( American made ones) lasted 12 years. They never caused me any problems. Checked the pressure every single time I pulled the trailer.

Just replaced mine that came on a 2K trailer - always garage kept and never a problem.
