This thread could go on, forever.
I wonder why so many people buy Airstreams? They are assembled with rivets. Rivets fail, we all know that. Must be Airstreams fault that rivets sometimes fail. So why in the world, do so many people buy Airstreams. There are many reasons, but they also know that when rivets fail, ONLY about 99 percent of the time, it's the owners fault, not Airstream.
I wonder how long a thread we would have if we posted about "ALL' the failures that Ford, Chrysler, and GM have had, and the hundreds of thousands of recalls they still have.
I am not defending Goodyear, but I, based on first hand experience, in my service department for many years, see improper inflation of tires, gosh, only about 98 percent of the time.
How do I know??
We do tons of running gear balancing. But before we start, we remove any rocks, sometimes nails that have not punctured the tire yet, and correct the tire pressure.
We find them any where from grossly under inflated to grossly over inflated. We correct the pressure to match the trailers loading, within reason, and within guide lines.
The average incorrect tire pressure, only runs about 98 percent.
Wow, and yet we sit back and blame the tire manufacturers.
Human nature, always has and always will, never place the blame for tire failures on themselves. Nah, that would be way to easy. Blame someone else, that's much easier, and makes for good conversation.
When we install new axles, we always take the owners running gear, and balance that for them at no charge. AMAZING,
the huge percentage, that are absolutely wrong.
Most owners, make sure the tires are inflated correctly, at least to their thinking, when new tires are installed. They will do that every time, they install new tires, and totally assume that's OK, until the next time they install another set of new tires.
PM, to all to many owners, means post-mortem, and rarely ever consider PM as meaning preventive maintenance.
We see every day, what seems to be, almost a total disregard for those two words.
24 foot Airstream that we received yesterday, that was brought in on a flat bed, was one of the best examples of almost total disregard for PM, that I have seen in quite a while, as well as other examples of ignoring important issues.
So the lug nuts came loose, so what. That caused one wheel to fall off. So??????
A quick examination showed that the axle, which was not the original, was grossly under rated, had no resiliency left in the rubber rods, had 10 inch brakes, with only the tires balanced. In addition, it had a huge cargo container added to the bumper, that took it's toll on the shell as well.
The drivers that loaded the trailer on to the flat bed, carefully chained the trailer to the bed of the truck, so that it could not move.
Unfortunately, the chains that were attached to the rear frame as it enters the rear of the shell, pulled the frame away from the shell, only about 4 (four) inches.
That clearly showed considerable rotten wood, as well as the frame still being about 2 inches below where it should have been, after the chains were remove.
PM, once again, what does it mean?
Lest we forget, ignore proper PM, and it will bite you where it will cause pain, when you sit down.
Unfortunately, when a low mileage new tire blows, the tread will not show that the tire pressure perhaps was incorrect.
So folks, lets back up a little, and examine "ALL" the possible causes of the tire failure and quit automatically blaming tire manufacturers.
I am not angry, but lets put the blame on ourselves, at least some of the time, where it really belongs.
We see, almost everyday in our shop, all to many examples of lack of even reasonable tire PM.
