Thoughts on this flat tire..

Check your valve stems too. They can look fine, but sometimes they can get caught and bent or ripped. I had a flat that took a while to show because I couldn't see it or hear it until I sprayed dish soap and saw that my valve stem was cracked.

 

be sure to take a video of you trying to hold down that large of a volume of air!

 

I off road, yet, all flats on my Taco have been on pavement. Take tire/wheel to a used-tire shop if you don't have road hazard warranty. They usually have a water tub to check for leaks. They will patch it from the inside and rebalance the wheel. $15 in my area.
Note: they don't actually balance it on the machine. They mark the tire and wheel and remount on the marks.

you can have a nail or something that will leak very slow, like takes a week or more, BUT if you park and the nail is on the bottom the shape of the tire because of the truck weight can make the hole open up more and tire can get flat faster

 

i do that when i take a bath

 

A screw is the worse- it goes flat pretty quickly.

 

When I lived in Montana the mountain roads would spread tires. Some of the stones were almost like arrowheads. Very hard on tires, I often carried two spares
