The tire model of the Buick Regal is 225/55R17. This vehicle is equipped with 17-inch dual five-spoke aluminum alloy wheels. The main functions of the tires are to support the entire weight of the vehicle, bear the load of the car, transmit forces and torques in other directions, deliver traction and braking torque, and ensure good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability. The Buick Regal has a length, width, and height of 4902 mm, 1863 mm, and 1456 mm respectively, with a wheelbase of 2829 mm. In terms of appearance, the car features a large-sized winged chrome grille that extends horizontally from the centerline. The shield-shaped upper grille echoes the trapezoidal shape of the lower grille, which expands outward, and together with the air curtain design on both sides, the front face presents a wide-body, low-profile sporty stance.

I previously drove a 2019 Buick Regal, and the tire model was typically P225/55R17, which was the type I frequently checked. The tire size for the Buick Regal can vary depending on the specific year and configuration. For example, higher-end models might use P245/45R18, which can be found on the label near the door or in the owner’s manual. I recommend that car owners regularly check tire pressure and wear, as incorrect tire sizes can reduce handling stability, such as making the car more prone to skidding during high-speed turns. When replacing tires, it’s best to choose the size recommended by the manufacturer—don’t just switch to larger tires for looks, as that could cause fuel consumption to spike. I’ve personally experienced a tire blowout due to excessive wear, so I always make a habit of glancing at my tires before driving. Nowadays, replacing tires is very convenient, as both dealerships and repair shops can help match the right tires for Buick models.

As a seasoned driver with over a decade of experience, I'm quite familiar with the tire specifications of the Buick Regal. The standard configuration typically features a P225/55R17 size, though this may vary by model year—for instance, the 2022 model sometimes uses P235/50R18. I find this size strikes a good balance between comfort and grip, making long-distance drives less bumpy. Tire specifications are crucial as they directly impact braking distance and safety. Using incorrect sizes, like excessive width, can make the steering heavier and increase fuel consumption. I recommend checking the label on the door jamb or the owner's manual for the correct size rather than relying solely on experience. Regularly inspecting tread depth helps prevent accidents—this practice has helped me avoid several close calls. When selecting new tires, brands like Michelin or Goodyear are fine, but it's essential to match the original factory size.

As someone who pays close attention to automotive safety, I often discuss the tire specifications of the Buick Regal. A typical size like P225/55R17 is a universal design that ensures stability and fuel efficiency. Non-compliant tires can lead to unresponsive steering and increase the risk of accidents. I always check the door label or manual to confirm the correct tire size, as changing the size can affect ABS performance. Regular maintenance saves money and provides peace of mind.
