2 Answers
2011 Nissan Sunny has three tire size models: 185/70R14, 185/65R15, and 195/60R15. The first number 185 represents the tire width of 185MM, 70 indicates the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width. The letter R stands for radial tire, and 14 represents the rim diameter of 14 inches. The 2011 Nissan Sunny has a top speed of 175km/h, accelerates from 0 to 100km/h in 12.8 seconds, and has a fuel consumption of 6.2L per 100km. In addition to the model, tires are also marked with the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
I recall that the original tire specification for the 2011 Nissan Sunny was typically 185/65 R15. This size represents a tire width of 185mm, an aspect ratio of 65%, and a rim diameter of 15 inches. When I drove this model, I found this configuration balanced comfort and fuel efficiency well, as the moderate aspect ratio absorbed bumps on city roads while maintaining stability at highway speeds. It's crucial to match the original size when replacing tires, as deviations can affect speedometer accuracy and even safety. I recommend checking the owner's manual or door frame label for confirmation, as specifications may vary across trim levels. From a technical perspective, rim size is critical—15-inch wheels are ideal for compact cars, providing good grip, but avoid excessively wide tires to prevent a sharp increase in fuel consumption. Regular checks of tire pressure and tread wear are essential for maintaining optimal performance.
