That seems to be the weight of the empty trailer - probably measured at the end of the assembly line. If I were you, I'd compare that to the GAWR's. I'll bet they are significantly lower.

Tires are all about fatigue. By underinflating a tire, you're using up some of that fatigue life - and the more underinflated you are the faster it gets used up. So if you discover that you had a tire that was running 45 instead of 55 psi, (about 20%), your best bet is to reinflate it and hope...

Your trailer came with side to side weights? From the factory? I've only seen GAWR's.

Barry's Tire Tech: The Physics (and Math!) behind Tires

Ppl No, it doesn't sound right. It's too far away from the 65 psi max. I would expect the value to be much, much closer. I did notice you didn't account for side to side and front to rear weight variation. There is so much we don't know about Frozen's situation. How did he come up with the...

Ah...... Mmmmm ....... Not exactly. You forgot to account for side to side and front to rear weight variation. Here, I tell how to do this: Barry's Tire Tech: ST Tires The starting point ought to be the vehicle tire placard. Then make modifications from there. Don't forget the Tire...

It appears you don't know that it doesn't matter who manufactures the tire, the load tables are the same. TirePressure.org: ST Tires

First, we tire engineers don't like the term "blowouts". The term is used in the public arena in so many ways, including times where the tire stays inflated. The number 1 reason for tires being removed from service is they are worn out. I don't know what percent that is, but it's about 80%...

I just wanted to thank you for your post about the NHTSA study on nitrogen. It has motivated me to do a deeper dive. Specifically, why are there 2 studies that have different titles, but appear identical? Are they really identical? What about the tires that failed before the DOT minimums...

Thanks. Interestingly, I have a copy of this exact report with a different title published in March 2009 (This report is Sep 2008) I suppose why I didn't remember this report was because it was pretty much a Nothing-burger. There were only a few interesting things in it.

Are you thinking of the Consumer Reports study? Internet Archive: Consumer Reports: Tire - Nitrogen Air Loss Study Yes, there are some benefits to nitrogen inflation, but not only have those benefits been exaggerated, but some of the supposed benefits aren't real! I go into more detail here...

Wayne, The only temperature limits I've ever seen published are for Extreme Performance and Racing tires. I think that's because the actual lower limit for normal tires is way below what we humans experience. This is not say the tires are optimal at very low temperatures, just that they are...

That seems like a reasonable result, but is there evidence that this actually takes place? Surely with all the winter/summer tire changeovers, there must be a lot of confirmation that this is true. But there isn't. Why?? I think it's because rubber degradation is very much temperature...

Ah, not exactly. More like 3 or 4 times. I've been working on a new webpage trying to cover this topic. It's difficult to explain and I need to figure out a way to do that. So, here goes: Tires are all about fatigue. The trick is to have the tire wear out before a fatigue failure takes...

Thanks. It seems to be my legacy. Not exactly, but from an engineering perspective, things could be better. That would reduce the risk. Good idea! Burst pressure is several times the max pressure. Yes, you could run 130 psi. I did a quick Google search and found several Load Range J...
