What is the correct TYRE pressure for 18 inch wheels?
The recommended tyre pressure for 225/40 r18 tyres can vary slightly based on the manufacturer and vehicle. However, a general guideline is to maintain the pressure within the range of 32 to 35 psi (pounds per square inch). 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.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.
How tall is a 245-45 R18 tire?
Therefore, the tire size 245/45R18 can be expressed in inches as roughly 9. Narrower and More Efficient 225 Tires. The width of 225 tires is less than that of 245 tires. There are several advantages to the narrower width. Fuel Efficiency: Smaller tires result in reduced rolling resistance, potentially enhancing fuel efficiency.
