What does 195/65r15 mean?
2 Answers
195/65r15 is a car tire specification, where 195 represents the tire width of 195MM, 65 represents the aspect ratio of the tire cross-section at 65%, meaning the cross-section height is 65% of the width, and r15 indicates the rim diameter is 15 inches. Below is relevant information about tire specifications: 1. Types of tires include: International standard tire codes, expressed in millimeters for the cross-section width and aspect ratio percentage. Followed by: tire type code, rim diameter (in inches), load index (allowable load-bearing mass code), and allowable speed code. 2. Generally, the larger the displacement of the vehicle, the larger its tire specifications will be. Of course, the size of the tire specifications will directly affect the vehicle's comfort, aesthetics, and its off-road performance. For small cars with displacements between 0.8-1.5, the corresponding front tire specifications range from 155/65R13-73T to 175/70R14-77H.
195/65R15 is a common way to denote tire specifications. The number 195 indicates the tire width of 195 millimeters—the larger this number, the wider the tire, which typically enhances grip but may also increase fuel consumption. The 65 represents the aspect ratio, meaning the height is 65% of the width, influencing ride comfort: a lower ratio offers more direct road feedback but a bumpier ride, while a higher ratio provides a softer experience. R15 signifies a radial tire with a 15-inch rim diameter, suitable for everyday family cars. I've driven with this size for many years and found it well-balanced for both city and highway use, offering decent handling without causing motion sickness for passengers. When selecting tires, it's crucial to match the original factory specifications—avoid arbitrarily switching to wider tires or larger rims, as this may lead to suspension rubbing or longer braking distances. Regular checks on tire pressure and tread wear can extend their lifespan.
