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.
Gear Ratio & Tire Size Chart. Good "rule of thumb" calculation is to mutiply .12 by your tire diameter. (.12 X 38" = 4.56) (see more formulas at bottom of page)

Automobile tires are described by an alphanumeric tire code (in American English and Canadian English) or tyre code (in British English, Australian English and others), which is generally molded (or moulded) into the sidewall of the tire. This code specifies the dimensions of the tire, and some of its key limitations, such as load-bearing ability, and maximum speed.
The values shown are calculated measurements based on the p-metric formula. Actual advertised tire height and tread width will vary from manufacturer to manufacturer for specific p-metric tire sizes.
The traditional sizing systems are based on a measurement of the outside diameter of a tire. This would usually be measured in inches (26", 27", etc.) or millimeters (650, 700, etc.).
The ISO/ERTRO number is the most important in determining if a tire will fit on a particular rim. The second number in the pair is the diameter of the rim measured where the tire bead will seat.

Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size.
