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.

Is 35 psi too much for tires?
Most passenger cars’ psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements. Good tire air pressure ensures that tires wear evenly, provide a smooth ride, and increase fuel efficiency.
Is 41 psi good tire pressure?
Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.

What happens if you put 40 psi in tires?
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.

What is the 4 psi rule?

What is a dangerously low PSI?

Does 5 PSI make a difference?

While 5 psi doesn’t seem excessively low, remember, 5 psi is usually about 20% of the tire’s recommended pressure.
What is the 6 PSI rule?
The 6 psi test for 4WD tyres*
If the tyres are correctly inflated, the pressure should have increased by around 6 psi above the cold pressure. If the pressure increase is more than 6 psi then your tyres are under inflated.
Why do dealers overinflate tires?
Tires are overinflated during the shipping process, so as to help prevent the flat spot from forming in the tire as it sits for days on in during the shipping process. It is supposed to be part of the delivery check process that the service department deflates the tires to the proper pressure.
