What is the tyre pressure for 245 45 R18?
Attached is a picture of the tyre pressure sticker from my F10 5 series, which has 245/45 R18 96Y tyres. According to this information, when carrying five people and luggage, the recommended tyre pressure is 37 psi (2. 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.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.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).car tyre pressure plays a vital role in safety, fuel efficiency, and overall driving comfort. Most cars require 32–36 psi, but the exact level depends on the model, load, and weather. Underinflated tyres increase fuel use and wear unevenly, while overinflated ones reduce grip and ride quality.But you shouldn’t go too much over recommended 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.
What vehicles typically use 245-40 R18 tires?
Numerous vehicle types, including sedans and premium vehicles, are compatible with 245/40R18 tires.

Switching to unnecessarily large tyres will not only affect your car’s mileage but may also impact handling and ride quality.Technically, drivers can interchange the tires with 225/245/265 sizes. However, before switching to larger or smaller tires, a driver should consult an expert in the field. Any size change involves handling and tire performance modifications that can mislead the driver, leading to serious risks.Generally, you don’t want to go with tires that have a diameter that is more than 3% different from the factory tires. It’s also a good idea to consult with a trusted mechanic before switching to larger or smaller tires.
What size wheel for 245-45 R18 tires?
Therefore, the tire size 245/45R18 can be expressed in inches as roughly 9. In your case, P245/45ZR18: The first three numbers (245) is 245mm and is the width of the tire measured from sidewall to sidewall with the tire mounted on the recommended width rim. In other words, the height of the sidewall is 45% of the width, or in your case ~110mm.In your case, P245/45ZR18: The first three numbers (245) is 245mm and is the width of the tire measured from sidewall to sidewall with the tire mounted on the recommended width rim. In other words, the height of the sidewall is 45% of the width, or in your case ~110mm.The 40, 45 number refers to sidewall height as a fraction of the width. So the /40 tire has a lower sidewall than the 45 tire. For the same rim diameter, the /40 tire will have a lesser overall diameter.Aspect Ratio): The tire’s sidewall is 45% of the tire’s width, which means the sidewall is about 114 millimeters or just over 4 inches. R (Construction Type): Radial tire, the most common type of tire produced today. Wheel Size/Rim Diameter): Going from edge to edge, the tire’s diameter is 18 inches across.Replacing a 245/40ZR18 tire with a 245/45R18 changes the sidewall height, increasing overall diameter by about 5%. This affects speedometer accuracy and may impact ABS calibration. Check wheel well clearance to avoid rubbing. Verify load and speed ratings match or exceed original specs.
Are 245 tires good?
Cornering Stability: The increased width of 245 tires improves stability during cornering, making them a great choice for drivers who enjoy spirited driving or frequently navigate curvy roads. Deciding between 245 and 255 tires is more than just numbers.
