Steel wheels' corresponding tire models can be analyzed through numbers and letters. Here are the detailed explanations: 1. Number explanations: "255" refers to the tire's section width, which is the distance between the two sidewalls, measured in millimeters. "18" indicates the rim diameter. "109" represents the load index, where different load indices correspond to different maximum load capacities, usually measured in pounds or kilograms. 2. Letter explanations: "R" refers to the tire's construction, indicating that this tire has a radial structure. "Y" denotes the speed rating, where different English letters represent different speed ratings.

What is the difference between the Rolls-Royce Black Badge version and the regular version?

Here are the differences between the Rolls-Royce Black Badge version and the regular version; Exterior: The Rolls-Royce Black Badge version, fully named Black Badge, is essentially the 'Dark Night Edition.' The Black Badge version features blackened treatments on multiple parts of the vehicle, including the Spirit of Ecstasy on the hood, the emblem, the grille, window frames, trunk trim, exhaust pipes, and more. Interior: For the interior, the dashboard is adorned with carbon fiber panels. These panels undergo six layers of paint, followed by drying, and are finally hand-polished to a mirror finish, a process that takes over half a month. The dashboard and seats feature the infinity symbol, representing the car's limitless design combinations and the boundless luxury of its manufacturing philosophy. The roof is made of black leather material, into which 1,344 individual optical fibers are handwoven to create a starlight ceiling effect. Mechanical: The Cullinan Black Badge version comes with an integrated active steering system, which is absent in the regular version. The engine remains a 6.7T V12, but after recalibration, it delivers a maximum power of 441 kW, 600 horsepower, and a maximum torque of 900 N·m, surpassing the regular version (420 kW, 571 horsepower, 850 N·m).

What is the fuel tank capacity of the Buick GL8 Landlord?

Buick GL8 Landlord has a total of 16 models currently on sale. Among them, the Land Business Class version has a fuel tank capacity of 66 liters, while other versions have a fuel tank capacity of 70 liters. This data is officially published, and owners who have purchased the Buick GL8 Landlord can also check it on the vehicle's configuration sheet. The Buick GL8 Landlord requires 95-octane fuel. The Land Business Class version has a fuel consumption of 9.5 to 9.9L per 100 kilometers, and a full tank can cover a distance of 667 to 695km. Other versions have a fuel consumption of 9.8 to 9.9L per 100 kilometers, and a full tank can cover a distance of 707 to 714km. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments left to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe limit. There is additional space from the safe limit to the tank opening, which is designed to allow for fuel expansion due to temperature increases without causing overflow. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity.
