In our Tire Talk forum, some of our readers have questioned the interchangeability of P-metric and Metric tire size designations. But answering this question is like asking how to solve the national debt crisis. In other words, there are many answers, and some might be more practical solutions than others. There are two major size designations commonly used for passenger car tires, called P-metric and Metric sizing. If you see a âPâ in front of the tire size displayed on a tireâs sidewall it is a P-metric tire. If thereâs no P, itâs a Metric tire (also called Euro-metric or Hard-Metric).
Some also use length in the same context as distance like when one says, âHold it at armâs length!â. Summary: 1.Length is describing how long something is while width is describing how wide an object is. 2.In geometry, length pertains to the longest side of the rectangle while width is the shorter side. 3.Length can also refer to an extent of time or a measure of distance. 4.The most common unit for measuring length is the meter.
