Definisi

Penjelasan

A tire marked 205/55 R16 has a tread width of 205 mm, a sidewall height of 113 mm (55% of 205), fits a 16-inch rim, and has a total outer diameter of approximately 632 mm. The mixed-unit format — metric width and percentage, but imperial rim diameter — reflects the tire industry's historical evolution across US and European standards. Load index and speed rating letters are often appended (e.g., 91V), indicating maximum load and speed.
