What does the tire size 21560r17 mean?
2 Answers
This indicates that the tire has a section width of 215 millimeters, an aspect ratio of 60, 'r' stands for radial tire, and 17 means it can be mounted on 17-inch rims. Here's a detailed explanation of tire size markings: 1. The international standard tire code consists of section width, aspect ratio, tire type code, rim diameter, load index, and speed rating. 2. Vehicle owners should pay attention to tire maintenance during daily use, regularly check tire pressure, and also monitor the tire wear indicators. When the tread wears down to the level of the wear indicators, owners should promptly replace the tires.
Last time I changed my tires, I chose a 215/60 R17. The meaning is quite simple: 215 is the tire width in millimeters, which is about 21.5 cm wide; 60 is the aspect ratio, indicating that the tire height is 60% of the width, so the tire appears thicker and provides a less bumpy ride; R stands for radial construction, which most cars use nowadays for better durability and fuel efficiency; 17 is the rim diameter in inches, and pairing it with 17-inch rims makes the car look more stable and elegant. This size is quite suitable for city driving, with decent fuel consumption control, but it's important to regularly check the tire pressure, as low-profile tires wear out faster and can affect braking safety. I often drive long distances, and this tire size offers great comfort and stability in turns, so I recommend it for regular family cars.
