    Keep going, make sure you’re not wearing safety goggles, also make sure not to read up on natural selection until after you’ve aired them up.

    Holy shit, 6.4 - 6.7 bar…

    Is this even possible?

      Road bicycles like the ones used in the Tour de France use pressures in the 120-140 psi range, but cars generally float around the 32 psi area.

        Probably less these days as it’s shown lower pressures and larger tires can improve performance.

        100 psi is standard on semi truck tires.

        Steer tires specifically are sometimes 110 or even 120.

        I just looked it up. It seems that normal car tires will explode at 115 - 145 psi.

          In not really talking about possible, I am more talking real world running pressure.

          I’m sure you can air up a car tire but at 90 psi it would be so rock hard that travel on it would be extremely uncomfortable. Also you would risk blowing it out whenever you went over a big enough bump. The tire volume inside would deform and cause a massive pressure spike.

          Tractor trailer tires are made with more layers of rubber and steel belting so they can safely handle higher pressures.

          Yeah you can definitely do it with car tires for a short time at least, that’s how you check for leaks (overpressure to like 80 psi and put it in a tub of water, look for the bubbles)

            You do not need to overpressurize to find leaks. This is dangerous advice, as a tire blowing at even lower pressures can kill you. And there won’t be any warning before it does.

              Sorry buddy but you’re full of shit, this is standard practice at tire shops. The reason you overpressure is that a tire at rest may not lose air noticeably, you overpressure to mimic driving down the highway when the tire is bulging out more due to centrifugal forces.

              80 psi for a few minutes is not really that dangerous, the tires blow up at 120+ psi.

    Sometimes I barely chuckle at the funniest things. And then other times I can’t stop laughing over the dumbest shit. Like this 🤣

    Use cold air so it’ll expand in the tire. Alternatively heat the tires, put them in the sun.

    • You need to inflate it to just over 100 so that the air that escapes when you pull the inflater leaves the tire at 100.

      An easy trick is to press in on the tire with your shoulder as you’re inflating; really push into it, and it adds just enough to offset the air loss when you stop inflating. Dad used to use his head, and that worked great because the smaller surface area of the top of his head meant more PSI, but I’m not as tough as dad and it hurts my neck to do it that way, so I use my shoulder.

      Anyway, don’t give up! You can get there, and a properly inflated tire can improve your mileage. Most people don’t keep their tires properly inflated and are just wasting money.
