Roger is pretty active over on the Airstream forums as well as several other RV forums. There is another engineer over there that goes by Capriracer or something along those lines, Roger goes by Tireman9. If you go to his blog home page there is days of worthwhile reading for anyone really interested in this sort of stuff, like me. I have read most of his blog in the past year or so. He outlines how to properly inspect a trailer tire and it doesn't involve just looking at it and kicking it, it's called the spin test and involves lifting it off the ground and doing some careful inspecting/spinning. He recommends this be done on a regular basis to find a tire in the early stages of separation instead of waiting for a blowout.
Another fun fact for the day: Did you know that nearly a quarter of the RVs weighed by the Recreation Vehicle Safety Education Foundation had loads that exceeded the capacity of the tires on the RVs? On average, these RVs were overloaded by over 900 pounds based on manufacturer specifications. In a separate survey conducted by Bridgestone / Firestone, 4 out of 5 RVs had at least one under inflated tire, a third of which were dangerously under inflated and at risk of failure

I've seen the "new, upgraded" speed ratings, but I will continue to tow at 62 - 65 mph because I feel safer. I have no need to go flying down a road at 70+ mph just to get to a campground a few minutes earlier. Just doesn't make any sense to me.

I believe this to be correct. ST tires are subject to far different stresses than a tow vehicle tire. Folks that have issues with their trailer tires have other issues than just the tires. Might have been before they took delivery, or because of some other factor, but still, once the damage is done, it's done. The other thing that I have noticed is the comments about how much heavier the upgraded tires weigh than the tires that came off...even 25lbs a tire is 100 more lbs of unsprung weight the springs and shackles have to deal with going down the road, and that is considerable, whether you think so or not. Are the experts on this and other forums really smarter than the guys that engineer this stuff? Sure costs come into play but there is far more that factors into this than most of what I have read here...it really is mostly opinions...and most don't make a whole lot of sense considering the whole scheme of things.
How many of you would have your coach if it cost another 20 or 30% more because is came with Goodyears and disc brakes and loomed wiring and all of the other things people complain about here...I'm certainly not an expert on this, or anything else, but I have not had a single issue with factory installed tires or the wiring or anything else, on any of my RV's, mostly because I maintain my equipment properly, and have been lucky as far as road hazards.
Also, I will add that I got a sweet coach I can enjoy for years, as long as I don't stress out over the small stuff...especially since much of the stuff I have to replace sometime anyway. I replace the tires on all my vehicles at 5 years or so, regardless. I haven't actually worn out a set of tires since I can remember. And I can't remember the last time I had a flat or any other tire failure either...
When it's all said and done, you can bulletproof anything you want, but there's always gonna be a downside, usually money and if you got it, go ahead and spend it but don't start pointing fingers and complaining. Most folks roll with what it comes with and it works just fine...2018 Reflection 303RLS
