Multiple Tire Blowouts
Hi all! Noobie to the forum but have been lurking for a while. Thanks for all the info you all share in this forum. It helps a lot more people that you know. So I have an issue.... We own...

Well, okay Cal, but let's just say that honest men shall disagree here. I see this whole load capacity thing in simpler terms. On the four trailers I currently run, one has 14", one has 15", the other two have 16". I have not had any problem choosing LT tires with adequate capacity, plus a safe reserve.
Let's use my most recent trailer as an example. 7500 GVWR. 3500 axles.
I use good year wrangler ht, 15" LT tires that are 2096 ( let's call it 2100 ) at 65psi.
For simplicity sake, let's assume it's balanced across all four tires, although it may not/probably not.
So I have 7000 pounds of axle capacity. I have 8400 pounds of tire capacity. 7K divided by 8.4K is 83%. I am happy with a worst case scenario of 17% reserve load capacity of my replacement LT tires. I know for fact, CAT scale verified, loaded for a show, with my quarter horse in the trailer, I do not have that much weight. More like approx 6K pounds or less, total including the tongue weight, which is of course carried by the truck, not the trailer axles. So the bottom line in this case is I have about 5300 pounds on the axles. I feel I am safely under all the stated limits.
As I have said before, numerous times on this forum, I would encourage each viewer here to take their rig to the scale so they know what they are really dealing with.
I have not seen any part of any of this, over the years, that goes beyond basic junior high school math.
As always, I really do consider these to be good discussions, because it often results in new trailer owners heading down the path of thinking, and research.
