Is 40 psi too high for tires?

Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure” of 33 psi, Gary. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.

Is 50 psi too much for tires?

Every tire has a rated maximum inflation pressure. Often it will be found in small print around the rim edge of the sidewall. … This means that the tire will safely carry up to 1477 lbs. and can be safely inflated up to 300 kPa (Kilopascal) or 50 psi (pounds per square inch).

Why do dealers overinflate tires?

Because the tires will wear out faster – so they get to sell you more tires. I noticed one day that my tires used to always wear a little more on the edges rather than in the center. So I started inflating them to 50 PSI. … Your tire pressure will go down about 1 psi for every ten degree drop.
