They don't ignore them. They are mashing that skinny pedal to get that truck somewhere they can get a new tire on the double before DOT sees it and puts them in an expensive and time consuming hole it may take weeks to dig out of depending on who they work for and the details of their operation. The incentive structure truckers work under isn't ideal to say the least.

If a truck driver stops to deal with a blown-out tire, they lose money. Delivery windows are incredibly short - there are bonuses for on-time deliver, and penalties for failure.

So at least some truck drivers will ignore a blowout, particularly if it's in the last couple of hours of a trip.

I agree and this is what I meant to write but alas, brain fart. Thanks for the correction!
