And the objective evidence for the above upgrades was.....?
The objective reality....the product works.
Yes, I have spent a lot of money now based on what amounts to mostly anecdotal (but quite alarming) reports of ST tire failures on Airstream trailers. I would have simply replaced my 15 inch tires with an equivalent load Michelin LT tire but they don't make them in 15 inch.
(XL P tires are not rated for a high enough load IMHO.) So, to preserve some load capacity in what should be a more robust LT tire I have had to move up to a 16 inch rim & LTE tire. I do not have good statistics to support this decision as the helpful, but not truly definitive, tire survey by Phoenix does not include a denominator in the failure column. (It can't). We have no way to know whether the lack of reports of Michelin LT tire failures is simply due to the relatively lower usage of these tires on Airstreams...
Nevertheless, there are enough reports of catastrophic LT tire blowouts on this forum alone that I am pretty sure that I will have a more reliable setup by going with the 16 inch LT Michelins.
I have ordered a TPMS system so that I can hopefully catch a leaking tire or overheating wheel before it fails. That can't hurt either - I don't think.
As for the Centramatic question though... I am aware that some folks feel that the contents of their A/S trailer are less disturbed and tire wear is less noticeable since putting on Centramatics; but, to date, I have not seen any sort of objective comparative to show that the Centramatics provide any meaningful benefit to the ride or wear of the A/S or its components.
BTW: The only objective test I could find online was a test using truck tires on a commercial Highway Rig in 110F heat with ~15% reduction in steer tire temperature using Centramatics vs the standard balanced tires. They probably do work but do they provide meaningful improvement for the Airstream trailer setup?
I started this thread in the hope that maybe someone, somewhere may have attempted to measure vibration, shake etc. before and after a Centramatics installation on an Airstream. So far, it doesn't look like it.
(The Dynabeads option is intriguing but even if they do work on a wider tire (i.e. non-motorcycle tire) I don't know that they would be compatible with the in-tire TPMS hardware.)
Interesting discussion though.
I appreciate the wisdom & experience of the collected voices on this forum.
