have you ever noticed how tandem axle trailers always seem to get objects stuck in the rear tire and seldom in the front?
my prior set of marathons picked nails up in the rears only, and most of our trailer tire problems at the power company seem to be mostly with the rears also.
i was told by my goodyear dealer this happens because the lead tire "stands" the object up and the rear tire gets punctured by it.
waddaya think?

The only 'proper' way to fine balance a tire is with 1 5/8" deck screws. Nails are a definite no-no. Use plenty of Vulkem when inserting the screws. Heads should be counter-sunk about 1/8".
Yes, my mistake. Always use zinc plated screws. Cadmium plated screws will do in a pinch, but zinc is more anodic and provides better galvanic protection.
Of course if you have a later model airstream with 5052 aluminum, then zinc is required, because cadmium is cathodic to the 5000 series.
I like those nifty balance weights that you just insert in the tire. What part number is that again?

O.K.- So which one do I use for 2024????

Hmmm, I've got a front tire on the trailer that has a nail in just like that, Andy - reminds me to get it fixed because I'm using the trailer next weekend - not bad because I only loose about 5 lbs of pressure a month.
If you have a tandem axle Airstream, 29 to 31 feet, reduce the tire pressure from 60 PSI to 10 PSI.
That saves 50 pounds of weight per tire, or 200 pounds total.
Now, if we replace the air in the tires with Helium....................fill an internal bag with Helium, we might be able to reduce the trailer weight thats on the ground to maybe 1000 pounds total.
Benefits??? Saves wear and tear on the tires, AND, reduces the load on the axle rubber rods, increases the 90 day or 500,000 mile (which ever comes first), to 200 years or 50,000,000 miles, which ever comes first.
Of course, as always, the warranty is good to the original owner, only.
And if you put in an adjustable water pressure regulator, you can reduce the water pressure from 45 PSI to 5 PSI, and save another 40 pounds. Also, let the air out of your spare tire to save another 60 pounds.
And loosen your lug nuts. All those ft-lbs really add up.
If you drain all the magic smoke out of the battery you can save a few more pounds. I don't recall how much an amp-hr weights, but I'm sure someone has the conversion factor. I think it's about 2.5 lbs per amp-hr.
