Neil deGrasse Tyson Explains Tire Pressure

Startalk always feels like a father teaching his son about the universe

Chuck was referencing wheel diameter, not tire width. A typical passenger vehicle tire is 195 - 245 mm cross-sectional. Also, the gross vehicle weight and tire inflation pressure is on a sticker in the driver's door jamb.

What kind of tires do you ride on?

When Chuck said "There's one problem, I do not give a d*mn how much my car weighs" I actually laughed out loud. Chuck deserves a PHD in the science comedy niche, other hosts can learn from him.

The editing on this video was AWESOME! Having the imagery pop in to match the explanations was a really nice touch.

My Uncle taught me about tire pressure. He asked me how much PSI I use in my car, and I said 35. He then asked how much I would guess he puts in his tractor's tire, I said it has to be like 200. .... he said, 8. "Surface area" It blew my mind.

At 8:53, I see that Neil was talking about the tire width which is usually around 225-255mm while Chuck thought you meant the diameter of the wheel which is usually around 16-20 inches, 17-18 is very common. For some reason rim diameter is measured in inches while tire width is measured in mm

Only Neil can make air pressure in bicycle tires interesting

It's minor, but the tires themselves also have support in their structure aside from air pressure, depending on the type of tire. That's how run-flat tires work.

"We dun paddled out, it's time to ride the wave" - Chuck 🤣😂🤣 Such an awesome guy.
