## What is a good PSI for water?

The pressure level can vary, but 60 PSI (pounds per square inch) is recommended for most residential homes. Water pressure should not be higher than 80 PSI.

## Is over 40 PSI bad?

For instance, if 35 psi is recommended, and the maximum safe pressure listed on your sidewall is 44 psi, you can safely put 38 or 40 psi in your tires. You can even go to 44 psi. You'll experience a harder ride, but you won't create a blowout danger. You may even experience sharper cornering and increased fuel economy.

In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles.
