3 Answers
The tire model of the Porsche Cayenne is 255/55R19. The first number 255 represents the tire width of 255MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, the letter R stands for radial tire, and 19 represents the rim diameter of 19 inches. The Porsche Cayenne has a top speed of 220km/h, accelerates from 0-100km/h in 4.58 seconds, and has a fuel consumption of 7.8L per 100km. In addition to the model, the tire also displays the following common data: Tire cord material: Indicated 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 of tires 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.
My Cayenne is the base 3.0T model with 20-inch wheels, and the original tires are Pirelli Scorpion Verde 265/50 R20. This model is quite common, focusing on quietness and comfort, with low tire noise on highways. During maintenance, the mechanic mentioned that the high-end models with 21-inch wheels use wider 315/40 R21 rear tires, likely Michelin Latitude Sport 3. When changing tires, don’t just look at the size—pay attention to the load index and speed rating on the sidewall. For a car like the Cayenne, you need high-speed tires with a W rating or higher. Last time I opted for a cheaper non-OEM tire, and the steering felt noticeably unstable. It’s best to stick with Porsche-certified tires marked with the N0 label. In the series of numbers on the tire sidewall, 265 is the width, 50 is the aspect ratio, and R20 is the wheel size. Just make sure to note these parameters when changing tires yourself.
Veteran performance car enthusiasts will tell you that Cayenne's tires depend on the specific model. The standard Cayenne typically comes with 19 to 20-inch wheels, mostly fitted with 255/55 R19 or 265/50 R20 tires, with Pirelli Scorpion series being the most common. The Turbo version is far more aggressive, featuring 275/45 R21 front and 315/40 R21 rear tires with thin sidewalls resembling sports car tires, often equipped with track-focused options like Michelin Pilot Sport 4 SUV. During track days, I've tested a Cayenne with 22-inch wheels—285/40 R22 front and 315/35 R22 rear—delivering strong grip but requiring caution over speed bumps. When considering modifications, avoid blindly upsizing wheels to prevent rubbing against the inner fender during turns. Always check the speed rating when replacing tires: Cayenne requires at least an H-rated tire, while Turbo models need Y-rated tires capable of handling speeds up to 300 km/h.
