View Here : How Are Tires Measured
Make sure the tire is completely inflated and is mounted on the vehicle. Measure the width of the tread of the tire. This is the distance from the tread's inner edge to its outer edge. Measure the diameter of the tire. This is the outside width of the tire. You place the tape measure from one end of the tire to the other across the center.

…for how to measure tire tread widths. And since tire manufacturers can use different methods, their published tread widths would only be meaningful when compared to other tires measured the exact same way. This makes it challenging to compare tread widths of one tire brand to another, and most tire…
Tire Width. Is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P215/65 R15 tire, the width is 215 millimeters.
Measure the tire from top to bottom for a precise measurement. Take the measurement over, not to the side of, the hub. Depending on your needs, you may also measure the hubcap in a similar way: start at the bottom of the hubcap and finish measuring at its tip. Use a stiff tape measurer to calculate the wheel diameter.
The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm.
Rims are measured in diameter and width, according to the tires they fit. Tires are measured by section width, section height or profile, rim diameter and tread width. Tread width merely notes the spread of a tire's tread as it meets the road, and doesn’t factor into rim size. Measure the rim width.
How to Measure a Bicycle Tire. Bicycle tire measurements have two components. The larger number is the tire diameter in inches, and the smaller number is the tire width in inches. Tire diameter usually ranges from 12 to 26 inches, and tire width normally ranges from 1.75 to 2.215 inches. The International Organization for Standardization (ISO)...
The Penny Test. In the United States, tire tread depth is measured in 32nds of an inch. New tires typically come with 10/32” or 11/32” tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models.
