What wheel size does a 155R15 tire fit?

A 155R15 fits a wheel of 15 inches in diameter. The wheel also has to be within the rim width range the manufacturer publishes for this size, which is printed in the tire's spec sheet.

What do the numbers in 155R15 mean?

155 is the section width in millimetres, R marks the construction (radial), and 15 is the wheel diameter in inches. This size states no aspect ratio, so its overall height is not derivable from the code — check the manufacturer's spec sheet for the fitted height.
