CART and F1 and maybe indy cars use a bleeder valve system that bleeds off the extra air pressure. I’m sure you can buy them but I would imagine they are pretty pricey. This helps on the start of the runs since they can keep the air pressures set to what they want for the whole run unless a yellow comes out.
