Automobile tires are an interesting case of measurement system compromise - the mounting diameter is measured in inches, but the section width is measured in millimeters. Sidewall height is even stranger - it's represented as a percentage of the section width.
Example:
195/60R15 - 15" diameter, 195 mm wide, and 117 mm sidewalls (60% of 195)
- hcarvalhoalves 14y agoTo my understanding, diameters are almost always measured in inches, even in countries that follow the metric system.
