Um, no.
Get a piece of sidewalk chalk.
Get your car on a flat, straight section of road in your neighborhood or a very large parking lot. Do this with tires cold (not driven on), morning is best.
Make a wide stripe ACROSS the tread (side to side) of each tire, but even a 1/4” stripe will do.
Drive your car STRAIGHT ahead, no turning of the wheel for fifty to 100 feet.
Stop the car, look at each chalk stripe.
IF the tire pressures are correct FOR YOUR CAR (not manufacturer’s recommended TP as these are always ridiculously low), the stripes will have worn evenly across the tire.
If TP is HIGH, center(s) will be worn/obliterated.
If TP is LOW, outsides will be worn.
Adjust TP accordingly.
Simple. EZPZ.
Neat trick

And how does that work for variable tire temperatures?
Reminds me....The other day I saw Alexandria Ocasio-Cortez waiting at a stoplight and one of her tires looked really, really low. I offered to help her change it. She stepped out of her car, looked at the tire in question, and said, “That’s okay, it’s only flat on the bottom.”
I tried that once. Chalk outline guy from the police department came by to help.
Manufacturers recommendation is typically a sweet spot between performance and comfort. Depending on your driving style and ride preferences you can typically go a few psi up or down. It’s a good idea to use the chalk method to verify thread wear.
