Trailer tire sealant??

Why? Unless you have a leak which obviously should be properly fixed its just a waste of money. Besides that once you use that crud the tire becomes unrepairable in the future.

Well it could also prevent a fast blow out that could tear the trailer apart.

Tire places HATE people who use that stuff. Its gooey and a mess to clean up when they have to change the tire. Most blowouts seem to be explosive blowouts on trailers that cause damage to the trailer in some aspect. Tire goo would do nothing but spray all over the trailer in that instance making a sticky mess. I would not use it but that's me, you can if you want.

would not use it, but you have to decide what is best for you. Also, you have decide what is best for the safety of everyone on the road.

Stick with QUALITY tires!

Cummins. That’s the problem. I don’t trust any tire manufacturers. The specs they claim do not standup under scrutiny.
I recently compared the stiffness of two tires. The higher side wall ply rating on one was easier to depress that the one with a lower side wall ply rating??
The tire shop manager commented they all have different standards regardless of claims.

Regarding a sticky repair. I have never needed to repair one. Once they leak or separate ( which has been my most often situation) I replace with new gamble.

None of them? Not to even be close?

A nail hole it may fix. A blow out, never

While I might use the fix-a-flat if I had a low tire and no way to change it, or repair it, I wouldn't use it until that actually happened. A TPMS is a better arrangement IMO.

Sorry, let me be specific. If a rear tire, perhaps at night is sloooly leaking, when it gets low enough, it will shred and tear things apart!
If sealant could save the destruction of your trailer it might be worth the goo.
