Did you know that since model year 2008, all cars have been required to have a light on the dash that tells you if your tires are under-inflated? According to Schrader, a company that makes sensors and valves, nearly half of consumers are in the dark about this little light.
It was news to me, too, thanks to my belief in buying used cars to save BIG -and then keeping them as long as possible to save even more. I don't have one of these on my dash, but I wish I did.
The dashboard symbol looks like a cross-section of a tire with an exclamation point inside.
And here's why you should care:
Worst case scenario, under-inflated tires can cause blowouts because the sidewalls sag onto the roadway and get beat up.
Soft tires wallow around on the road, causing too much contact and friction and using up gas.
When your tires are under-inflated, they give your vehicle a sloshy, wallowing ride that's not only unpleasant but unsafe.
Under-inflation can also hurt braking distance, so that it takes longer before your vehicle comes to a stop.
