PSI is a nice scale for tire pressure since most tires will be between 20-100 PSI. There’s pretty much never a reason to use decimals, and 5 PSI is the most useful increment.
Bar is probably nicer for a bunch of other things, but for everyday use, PSI has a nice scale. That’s also why I prefer Fahrenheit to Celcius for weather, but Celcius for cooking and science.
