I have a front wheel drive Chrysler. The weight up front squishes the front tires enough so they look under inflated.
Rather than get out my pressure gauge every time the tires look like they’re going flat, I got some valve stems that are really neat. They are rated for 32 psi and have green little rims that go red if the pressure drops a certain amount. You can tell at a glance if the tires are low or not. Tres cool.
Mine has the square stick that pops out.
