What is the tire size of the Panamera?
2 Answers
The Panamera has four tire size models: Panamera 2023 Panamera 2.9T - front wheel 265/45R19, rear wheel 295/40R19; Panamera 2023 Panamera 2.9T Platinum Edition - front wheel 275/35R21, rear wheel 315/30R21. In 265/45R19, the first number 265 represents the tire width of 265MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 19 represents the rim diameter of 19 inches. The middle letter R stands for radial tire. In 295/40R19, the first number 295 represents the tire width of 295MM, 40 indicates the aspect ratio of the tire section is 40%, meaning the section height is 40% of the width, and 19 represents the rim diameter of 19 inches. The middle letter R stands for radial tire. In 275/35R21, the first number 275 represents the tire width of 275MM, 35 indicates the aspect ratio of the tire section is 35%, meaning the section height is 35% of the width, and 21 represents the rim diameter of 21 inches. The middle letter R stands for radial tire. In 315/30R21, the first number 315 represents the tire width of 315MM, 30 indicates the aspect ratio of the tire section is 30%, meaning the section height is 30% of the width, and 21 represents the rim diameter of 21 inches. The middle letter R stands for radial tire. Every component of a car requires maintenance, and car tires are no exception. We need to regularly clean stones from the tire treads, check if the tire pressure is standard, and observe the wear condition of the tire surface to replace tires in time. Avoid driving on extremely poor road conditions. The standard tire pressure for the Panamera is between 2.3-2.5bar. According to the principle of thermal expansion and contraction, the tire pressure should be controlled at around 2.5bar in winter and around 2.3bar in summer. The Panamera uses Nexen tires, which have strong grip performance. 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 tire. 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. Common 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.
When driving my Porsche Panamera, I found tire size to be quite crucial. Taking my personal 2021 model as an example, the front and rear tires are 245/45 R19 and 275/40 R19 respectively. This configuration is excellently designed, providing stable cornering without excessive bumpiness. In the tire size, the number 245 represents the width in millimeters, 45 is the aspect ratio percentage, and R19 indicates the rim diameter in inches. Remember, the size directly affects handling and comfort—if you arbitrarily change to larger or smaller sizes, you may feel the steering wheel become heavier or experience increased bumpiness during long drives. It's advisable to check the label near the door during every maintenance session, as there might be slight variations between different years and models like the Turbo or 4S versions. My experience is that sticking to the original factory size ensures both fuel efficiency and safety.
