The Difference Between Euro-Metric and P-Metric Tire Sizing

The Difference Between Euro-Metric and P-Metric Tire Sizing

It is not enough that we give you cheap wheels and tires , providing helpful details about the products we sell is something we commit on giving best.

Have you check the tire sizing description and wonder what it means? Let’s say you have been given P225/60R16 and 225/60R16, both of it were tire sizes but here are the definition to describe the difference between the two.

The first example of tire size is noted with a letter “P” at the beginning, this is an example of a P-Metric Tire Size. P-Metric sized tires are those with a character “P” at the beginning of the description. They initially became popular in the US in the late 70s. P-metric sized tires are usually used and installed to vehicles that are carrying passengers. This includes passenger vehicles, sport utility cars, station wagons, and also light trucks. The capacity of the loads depend on engineering formula that considers its physical size, also referred to the volume of space for air within the tire, as well as the amount of air pressure. Because all available P-metric sizes depend on the formula for its load, car manufacturers could outline their vehicles based on existing or newly made tire sizes.

The other tire size is called Euro-metric, also called as Metric. It is a tire size without the “P” in the beginning of the tire size description. The dimensions being used for Metric sized tires depend on the tire width and originated in Europe around late 60s. But Euro-metric sizes have been introduced depending on the load capacity and dimensional measurements of newly manufactured vehicles, so this makes the tire manufacturers create more tire sizes and capacities for load based on the vehicle’s needs. The two tire sizes mentioned are within the same size measurement, but slightly differ from its load capacities and inflation pressure calculations.
Always remember that as much as we want to suggest you all the details mentioned, it is also best for you to refer into your vehicle’s manual for the highly recommended size tires.
