The pressure from an exhaust pipe is <0.17 bar or 2.5 PSI.
My car tires have to be pressurized to 2.3 bar or 33 PSI.
So what happens is you get a flat tire that smells funny. And if you are doing that in a garage, you’ll probably get carbon monoxide poisoning.
Factor error: 33psi is about a typical car tire pressure. Race bicycles are like 120. Please keep 330 away from rubber
Looks like google helpfully stripped away the “.” in 2.3 bar because my locale wants me to use a “,” instead.
2.3 bar != 330 psi
But the point still stands. 0.17 bar / 2.5 PSI is not enough to inflate a tire.
You’d fill a tire with pretty low pressure, dirty, mostly co2, I’d assume. It probably wouldn’t be drivable and even if it was the small amount of oil and fuel residue would likely damage the inside of the tire after a while.
There are some cool gadgets that you screw into a spark plug socket in the engine and crank it over with the starter to inflate a tire. You’d want to unplug the fuel injector(s) or you’d be turning the tire into a bomb.
The sherp vehicle does just that.
There’s going to be a limit to how much pressure before stalling and/or damaging the engine, but it would inflate, and as the gases cooled, it would deflate somewhat.
Exhaust jacks are used in 4x4 recovery, so an engine can lift a car, but they seem pretty limited and dangerous and I’ve only seen one used once in my ~25yrs off road.
Okay hear me out, I know this is funking stupid but what if: We only use a portion of the exhaust and make some sort of system that can feed the gas to when wheels are spinning and monitor the pressure at the same time, then add a lining on the inside of the tires to protect the rubber.

Rotating seals are always a pain in the ass.
Yeah, these guys suck.
