What is the lowest tire pressure you've ever driven on?

Just got home and my tire was at 10psi, so I clearly hit something while on the road.

Anyone here ever driven on a completely flat tire?

I would think if you had a sudden loss of pressure due to impact, it would be 0psi not 10.

I've driven with one tire on 23psi before.

ETA: And obviously I'm not counting driving on 0psi after blowouts, which has happened to me twice.

Zero

But it wasn't far, maybe 100 yards

Yes and it will destroy the sidewall of the tire.

I lost my balance while I was filling a tire and ripped the valve stem off Drove on the rim for a block on a service road to get to the Firestone.

On the flip side, my wife had filled one of her tires to about 90psi when the pressure light wouldn't turn off. What she didn't realize is that the tires had been rotated and not recalibrated, so the Front Left was now on Rear Right. Still not sure how it didn't explode when she hit a pot hole.

Was on I-10 in New Orleans a couple weeks ago and saw my tire pressure warning was at 24 psi. Told my wife to look for a gas station and in the process saw it start going down to 22, 21, 20, etc. Thought, "Oh frick!" Took the next exit onto City Park Avenue and then turned on to Canal and pulled into the closest station. By the time I stopped I was around 6 psi.

6, apparently the pressure won't go any lower than that as the tire was completely void of air, but the thickness of the rubber still allowed it to get me to an air pump.

When I filled one of my tires the machine said 6, but to be honest the tire did not look like it was on 6

Doesn't everyone on OT have run flat tires?

10 is a flat tire.

0 is no pressure at all. 0 might be a vacuum since anything less than 14 is below atmosphere.

There’s 14 psi in the air at sea level. I’m not sure how they’re calibrated but in theory tire pressure can’t be lower than 14, and at 14 you’re flat. Unless when it says 0 it’s at 14 and anything above 0 is really 14 + whatever the sensor says.

Pretty common to offroad with 8-10 psi, lower with bead locks. Even drove back to the hotel (slowly) with only 10 pounds in a 35x 12.5 R15.

On the road, no air in tire on a runflat, only lasted about 2 or 3 miles at 45 mph. Piece of crap tire didn't hold up for shite. Don't believe the claims. I bought a spare and put it in the trunk after that experience.

Bridgestone Dueler run flat got me about 20 miles from a blowout on a highway back to my house. Including highway and surface street driving. The everyday ride is not great but it did its job when I needed it to.

I've pulled the valve stems a few times and rode for hours. I usually run around 2 or 3psi.
