What's currently the fastest Porsche?
The recommended psi for my car tires is 30. But i realize that its hard to achieve it because i initially take the pressure with a guage, then add some air, then let out some air, then take the pressure again. Is there anyway to inflate to the correct pressure without all the hassle? And will a higher psi lead to better fuel economy?
