I hope not. If that is the case, than every trailer I pull has eight flat tires according to DOT. The big box store company I pull freight for only fills their junk recap tires to 80 psi. I hate it. I usually fill them to 110. But it is every freakin trailer.

Yes its true.. got inspection 1 time in i44, mo exit 4 scale.. that day they just went around check tire pressure only.,summer season. he told me if any 10% less than manufacture print on the tire.. there will be citation..
Let say the tire print 100 psi in cold.. he measure 90. Got ticket
The thing is when inspection.. tire was hot.. so if it is 90 psi whick meant when cold i am pretty sure it way below that..
