Once your new tire pressure is dialed-in, it can’t hurt to write it down and keep a copy in the glovebox. Then anytime you want to air-down, you won’t have to rely on your memory when you need to fill up before hitting the pavement. It can also come in handy for anyone who ends up borrowing your truck. You may want to keep the chalk in your vehicle, because you’ll need to use it again in about 500 to 1,000 miles after the sidewalls have broken-in and make sure your truck’s preferred tire psi is still the same.
