What does 23560r18 mean?
2 Answers
23560r18 is a tire specification, indicating that the tire's cross-sectional width is 235mm, the aspect ratio is 60%, the tire type is radial, and the rim diameter is 18 inches. Tire specifications are generally located on the sidewall of the tire, showing the section width and aspect ratio in millimeters, followed by the tire type, rim diameter, load index, and speed rating. Car tires are one of the important components of a vehicle, directly contacting the road surface and working together with the car suspension to absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, thereby improving the vehicle's traction, braking, and off-road capability.
As a seasoned driver with years of experience, I find this issue quite common. 23560r18 actually refers to the tire size specification, but it's often written as 235/60R18, just missing the slash. Here, 235 is the tire width in millimeters—wider tires generally offer better grip but increase fuel consumption. The number 60 represents the aspect ratio, simply put, the percentage of the tire's height to its width. A smaller number means a thinner tire, which improves handling but makes the ride stiffer and less comfortable. The R stands for Radial, indicating it's a radial tire, which is what most cars use today. The 18 denotes the wheel diameter in inches, which determines the overall height of the tire. Matching the wheel diameter is crucial, as sizes too large or small might cause rubbing against the fender. Judging by this size, it's commonly used for SUVs or some family cars. I've used 235/60R18 tires before—they provide stable acceleration but can be a bit bumpy over speed bumps. I recommend checking the manual to match the original factory size when replacing tires to avoid safety hazards and significant differences in fuel efficiency.
