A tyre company has developed a new tyre cap that changes colour when the pressure gets too low.
The tyre has a spring-loaded mechanism tucked inside of a sealed housing, a ring around the core of the cap changes from red, to black, to yellow depending on your tire's pressure. Red means too low; yellow means too high. When the cap is black, you're good to go, Tech Crunch reported.
The sole catch is that these things have to be tuned for your tire's optimal PSI before they leave the factory, which means if an owner wants to swap them onto a different car or buy different tires, they need a new set.
The company claims that the owners can tune the cap to any PSI level, but it can't be changed post-production.
