I pulled my utility trailer with my 4 wheeler on it from sandy hook ms(north of Bogalusa) to Covington with no air in one of the tires. By the time I got to Covington there was a shred of tire on the outside lip of the rim and that was it. Luckily it was in the middle of the night.

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



It's a gauge pressure.

The zero mark is equilibrium with the atmosphere. How else could air keep leaking from the tire if the pressure in the tire is lower than the surroundings.

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


most people dont realize the lower the tire pressure gets the easier it loses air. that is because many valve stems have cores that have weak springs so the tire pressure helps seal the valve core from leaking. over time all tires lose air, but once you get below 20 lbs it tends to escape quicker so you may have been low for a while and never noticed it.

i think 10 lbs is about the limit before the tire starts looking flat and you can feel it when you drive

Wife had not one, but 2 blowouts over the course of 6-8 weeks. She swore she didn’t feel anything different. I have no idea how she possibly couldn’t have. Thank god for Tire Warranties

Zero.

Blew a tire on the Dallas North Tollway.

Fun stuff if you've never tried it.

Drove in on 19 this morning. I knew it was low just too lazy to fill it up this morning. Plus didn't feel like sweating in my work clothes.

Anyone here ever driven on a completely flat tire?


do you not understand what that will do to a rim and what the rim will do to the tire?

I used to not give a frick. I would drive on a flat tire to the gas station to use the air compressor to fill the tire back up.

I have a tire that keeps getting low even though the dealer "patched it". If it gets below 25, I start to worry. I have an air compressor that plugs into the cigarette lighter (do we still call it that?) which I keep in my truck at all times.
