What is the difference between R16 and R18 tires?
1 Answers
R16 and R18 tires differ in diameter, fuel consumption, and safety. The 'R' stands for radial tire. Diameter difference: R16 indicates a wheel hub diameter of 16 inches. R18 indicates a wheel hub diameter of 18 inches. Fuel consumption difference: R18 tires consume more fuel than R16 tires. As the diameter increases, the wheel rim becomes heavier; larger rims may also lead to wider wheel hubs, which in turn require wider tires, ultimately increasing fuel consumption. Safety difference: R18 tires have a wider tread, improving grip, and lower aspect ratio, resulting in higher safety performance.
