What is the rim size of the BMW 5 Series?
1 Answers
The rim size of the BMW 5 Series is 17 inches with a bolt pattern of 5×120, and it can be upgraded to 18-inch rims. Larger rims have stronger load-bearing capacity: Smaller rims often use steel materials to save costs, while larger rims are typically made of aluminum alloy, especially those manufactured through forging processes. The load-bearing capacity of such rims is five times that of ordinary steel rims. Larger rims may reduce ride comfort: Large-sized rims can affect ride comfort. Generally, the outer diameter of the tire is a fixed value, meaning the larger the rim, the thinner the tire sidewall. This results in poorer noise isolation from road vibrations, leading to increased cabin noise and reduced interior quietness.
