# Rim and Tire Sizes Standards

There exist industry wide standards to ensure that tires and rims will fit uniformly regardless of who made them or where they were made.   Standard tire sizes which are recommended for use on specific rims are in the chart below ...

## Recommended Tires for Rim Sizes

This chart is designed to answer the question: “What sized tires can be used on a certain rim size?”

To use it locate the rim diameter in the first column, then the rim width in the second column.   The tire sizes which are recommended for use on that rim are listed to the right ordered according to the tire width in ascending order.  Standard tire sizes are always written as WW/AR DD, where WW = tire width in millimeters, AR = Aspect Ratio, and DD is the rim diameter which the tire is made to use.   A typical example is 205/65 R15.

There may be some letters in front of the size which signify that the tire is designed for a certain use, and the letter R before the rim diameter may be missing, or could be B or D to indicate that it is of Bias or Diagonal construction.

Note these are recommended sizes for the rims based on standards published by the European Tyre and Rim Technical Organization (ETRTO).  Permitted sizes will be sizes which are close to recommended tires (possibly + or - 10 mm in width) and may be verified by consulting the permitted rims section of a rim diameter or aspect ratio chart and locating the specific tire under consideration.

The letter following a Rim Width (example "B" in 4B) refers to the flange style which the rim uses.

### J Flange = JK Flange

Where J flange rims are specified, JK flange rims may also be used.

Rims for passenger cars are marked with either the width or the rim diameter first, as in

4½J x 15

or

15 x 4½J

where  the width is 4½ inches, the flange profile is J and the rim diameter is 15 inches.
