Them slowly getting a flat is not going to cause an accident. The low pressure warning is gonna come up well before anything dangerous actually happens

Probably still not going to cause an accident, but not all vehicles have low pressure warning systems. My car doesn't.

[–] [email protected] 2 points 6 days ago (1 children)

They all do. Maybe not an LED, but I promise you'll get a warning anyway as soon as you drive.

Apparently this is a 2007 thing, my car is a 2005. I promise you it doesn't.

If your car leans to one side, that's your warning.

That and the change in ride and hissing is a pretty obvious giveaway too that something is up

source: got a couple of flats in vehicles that dont have tire pressure sensors

Most do, obviously excepting older vehicles. It's mandatory per Federal law in the US since the 2007 model year, and I believe the 2014 model year in the EU.

Still, in the nearly a century prior people managed to deal with unexpected flat tires and slow air leaks even without such electronic geegaws just fine.

And my truck is a 1999. And none of my motorcycles have TPMS, either.

And yet, neither of us are dead.

Ok, I'm the guy who said it probably wouldn't cause an accident so it's not like I'm going to disagree with you.

Fair enough but still it’s not gonna be like a blowout

[–] [email protected] 2 points 6 days ago* (last edited 6 days ago)

Eventually it might because we're human, cheap and, stupid.

  1. tire is slowly deflated
  2. driver doesn't notice it and drives on the flat damaging the sidewalls or driver does notice it but drives on the flat anyway to get to safety/a repair place
  3. reason for deflation is found and corrected.
  4. tire with damaged sidewall is refilled with air and driven on.
  5. At some point in the future, under stressful conditions that the tire normally could handle the sidewall gives out in a catastrophic blowout.

Lol, it's a government vehicle. I'd be willing to bet that warning is on all the time. The sending units are integrated into the valvestem and cost a lot more than old school valvestems.

[–] [email protected] -1 points 6 days ago

Even retail they're only like $25 a pop, which granted is more than the buck-or-less of a normal rubber valve stem but probably pretty negligible if you're on a government budget. They're less in bulk. The real bitch is you need to dismount the tire from the rim to get at it, then remount and balance it. And then get the vehicle to learn the new sensor ID code which for some vehicles can't be done onboard and requires a separate gadget.
