What does 65r17 mean?
2 Answers
65r17 is the specification of a tire. 65 refers to the aspect ratio of the tire, meaning the section height is 65% of the width. R indicates that the tire is a radial tire, and 17 refers to the rim diameter of 17 inches. Related information: 1. Introduction: A tire is a circular elastic rubber product mounted on various vehicles or machinery to roll on the ground. It is usually installed on a metal rim to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. 2. Precautions: Develop the habit of checking tire pressure regularly. Air pressure is the key to extending tire life—if the tire pressure frequently exceeds the normal pressure by 20%, the tire's lifespan will decrease by 10%; if it is often 30% below the normal pressure, the tire lifespan will decrease by 52%.
When you mention 65r17, I naturally think of tire size. I've driven many cars, including my old SUV, where similar markings are common on tires. That 65 usually represents the aspect ratio percentage, indicating the height of the tire's sidewall relative to its width—a higher value generally means more comfort but possibly softer handling. The R stands for radial construction, which is almost universal nowadays, offering durability and stability. The 17 refers to the wheel diameter in inches. When changing tires, it's important to note the full size, such as '225/65R17', including the width for accuracy. Choosing the wrong size can affect driving safety, potentially causing wobbling or increased fuel consumption. I recommend checking the tire label for confirmation, and if unsure, ask a mechanic. In short, understanding these numbers can save you from big troubles, saving money and giving peace of mind.
