What does 225 45 R17 mean?
The first three digits (P225/45R17) is the tire’s section width. This is the measurement in millimeters from the widest point of the inner sidewall to the widest point of the outer sidewall. The second pair of numbers (225/45R17) is the tire’s aspect ratio or profile. Typically, low profile tyres have an aspect ratio of 50 or lower. This means that the height of the tyre’s sidewall is only half or less than the width of the tyre.Aspect Ratio (55, 45) In our examples, 55 and 45 indicate that the tire’s sidewall height is 55% and 45% of the tire’s width, respectively. A lower aspect ratio typically indicates a shorter sidewall and a wider tread, which can contribute to improved handling and responsiveness.Technically speaking, a low-profile tire has a shorter sidewall compared to its tread width, typically with an aspect ratio of 50 or less. For example, a 225/45R18 tire has a sidewall that’s just 45% of its width.Width – The tyre’s tread width, ensuring stability and road grip. Aspect Ratio – The height of the tyre’s sidewall is 45% of the width, offering a low-profile design for better handling. R (Radial Construction) – The most common and durable tyre type, ensuring longevity and performance.
What is the price of 225 45 R17 tyre?

You will also have the option to include other services like Wheel Alignment and Wheel Balancing. The R in 225/45/R17 indicates that the internal structure of the tyre is radial while the 17 shows that the wheel to which the tyres will be fitted needs to be 17 inches in diameter. The 225/45/R17 tyre pressure in most models should be in the region of 32 PSI or 2.R17 tires have a diameter of 25 (634 mm), a tread width of 8. The sidewall of the tire is 4 (101 mm), and the tire’s circumference is 78. This means a 225/45R17 tire will make make 807 revolutions per mile, or 502 revolutions per kilometer.
Is 45 too high for a tire?
Most passenger vehicles fall between 28 and 36 PSI when cold. PSI is generally typical for small car tires, while 36 PSI is appropriate for medium-sized vehicles. Proper pressure in larger vehicles like SUVs, crossovers, and light trucks falls between 35 and 45 psi, depending on their weight and size. 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.Medium-sized vehicles such as SUVs and crossovers usually need a slightly higher tyre pressure, typically between 35 to 40 PSI. This supports the additional weight and size of these vehicles, ensuring stability and control.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.While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree). Your car may have different ideal tire pressures for the front and rear axles.
