The tire model of the Buick Regal is 225/55R17. The Buick Regal is equipped with 17-inch dual five-spoke aluminum alloy wheels, and it comes with Goodyear's EfficientGrip series tires, which are designed to focus on grip and quiet performance. The Buick Regal is a B-class sedan launched by Buick, with body dimensions of 4902mm in length, 1863mm in width, and 1456mm in height, and a wheelbase of 2829mm.

As a seasoned driver who has owned a Buick Regal for many years, I can confirm that the typical tire size is 245/45 R18. For example, my 2018 model uses this specification. Tire dimensions significantly impact driving safety - the 245 refers to a tread width of 245 millimeters, the 45 represents the aspect ratio (indicating the tire height is 45% of the width), and R18 denotes 18-inch rims. This size was chosen because it ensures comfort during daily driving without being too bumpy while enhancing handling, especially during cornering. When replacing tires, I recommend using manufacturer-recommended brands like Michelin or Goodyear, which typically last about 50,000 kilometers. Regularly check tire pressure and maintain it around 240kPa to save fuel and prevent premature wear. From experience, altering tire sizes puts extra stress on the suspension system, so never casually change specifications during replacement. With proper maintenance, tires can significantly enhance the overall driving experience.

How to Solve Fogging Inside the Car?

Turn on the defogger, you can turn on the car's air conditioning and select the defogging mode for quick defogging. Generally, during rainy weather, fogging is caused by the large temperature difference between the inside and outside of the car. You can lower the temperature of the air blown by the air conditioning to keep the indoor and outdoor temperatures close, achieving defogging. Without lowering the temperature inside the car, you can choose the mode of blowing the windshield and the feet to continuously prevent fogging in the cabin.

At this point, immediately turn off the compressor clutch power supply and check if there is any leakage in the system. If not, it may be an issue with the oil circuit. In this case, check if the oil pipe is crushed or twisted. If not, it should be caused by a clogged oil drain valve on the evaporator pressure control device, which then requires repairing the oil drain.

How to Identify the Age of a Vehicle?

Methods to identify the age of a vehicle: 1. To determine the age of a vehicle, simply check its manufacturing date; 2. You can look at the nameplate on the B-pillar, which usually has this information, and it can also be found on the nameplate inside the engine compartment; 3. The registration date of the vehicle can be seen on the vehicle registration certificate and the owner's driving license. Many parts of a car are produced by suppliers. After the suppliers produce the parts, they are sent to the car manufacturer, and then the workers on the production line assemble them. The manufacturing date of the entire vehicle is definitely later than the production dates of its parts. Many components of a car have detailed production dates, such as tires, glass, radiator, radiator frame, air conditioning compressor, generator, and headlights.
