Rim width and tire width are two closely related sizes. Flexible tire sidewalls alow a single tire size to be mounted on a rim of various widths.
National technical standards regulations. The European Tyre and Rim Technical Organisation (ETRTO) and the Tire and Rim Association (TRA) are two organizations that influence national tire standards. The objective of the ETRTO include aligning national tire and rim standards in Europe. The Tire and Rim Association, formerly known as The Tire and Rim Association of America, Inc., is an American ...
A useful chart for determining the tire size you need for your bicycle.
Alpha numeric tire sizes were introduced as Original Equipment in the late 60s and became widely used in the early 70s. These tires were identified with a letter which indicated the tire's load capacity, followed by an "R" if radial ply construction, the tire's aspect ratio and wheel diameter.

Sidewall Markings. There is a lot of information on the sidewall of a tire. Typically, you'll find UTQG ratings for treadwear, traction and temperature, the size of the tire, the load rating index number with a speed rating index, the construction type (bias or radial), the D.O.T. (Dept. of Transportation) compliance code, construction details, and of course, the make and model of the tire.

Tire Size Calculator To use the Tire Calculator, enter the top part of the data into the form. For Example a tire size of P245-45R-17 would make you Enter 245 for the Width, 45 for the Aspect Ratio and 17 is the Rim Diameter.
Find your sidewall width or size in left column. Move right to find your Aspect Ratio column (AR, may be on the sidewall or mfg.’s specs). Number in the box + your rim diameter = tire’s outside diameter (height).
Use this table to determine the tire size that can fit your rim.
