Is 40 psi too high for 4WD?
Choosing the Right Tyre Pressure for On-Road Driving For everyday bitumen driving, most 4WDs should run between 30 and 36 PSI when the tyres are cold. Here’s a rough guide: Light load (just a driver and a light pack): 32-34 PSI. Heavy load (extra passengers, gear, roof racks): 36-40 PSI. Each vehicle has its own specifications for tyre pressure, but most fall between 28 and 36 PSI (pounds per square inch) however this could be greater especially if you carry extra load in your vehicle or run on larger diameter wheels (there is usually another pressure recommendation for these or the placard).
Is 40 psi too high for tire pressure?
No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi. You can safely over-inflate tires by up to 10%. For example, if your tires have a recommended PSI of 35, you can go up to around 38 PSI without worry. Anything more than that is too much and not recommended.
