This happened halfway through my shift. I did a proper pre-trip dumb ass. I've been dong this 45 years and I know what the I'm doing. Does a blowout of a steer tire mean you didn't do a proper pre-trip? It probably happened when I made a hard right turn. Something's just wear out dumb ass.
If you bothered to look at the grommets you can see what shape they are in.
Ive been doing this for 31 years and rubber grommet that were in good shape have never started leaking to the point it was draining all my air, after i checked them for leaks. I inspect them upon my pretrip and if they look worn or beat up i replace them. And then i check for leaks.
Try it, it works. Lol
Also scraping grease from the lip of the trailer onto them can stop most leaks.
