The original tire model for the Buick Regal is the EfficientGrip Performance series in size 225/55R17. The Buick Regal is equipped with 17-inch dual five-spoke aluminum alloy wheels, paired with Goodyear's EfficientGrip Performance series tires, which prioritize grip and noise reduction. The Buick Regal is a B-class sedan introduced by Buick, positioned between the Excelle and LaCrosse. In terms of safety features, this vehicle is equipped with ABS+EBD, airbags, side curtain airbags, an electronic parking brake, etc. For comfort and luxury features, it includes an 8-way power-adjustable driver's seat, 4-way active safety headrests, 4-way power lumbar support, driver's seat memory function, and more. In terms of powertrain, the car is powered by a 1.5T and a 2.0T turbocharged engine, with the 2.0T engine delivering a maximum power of 192 kW and a maximum torque of 350 Nm. The transmission is a 9-speed automatic manual transmission.
I've been driving a Buick Regal for many years, and the original tire specifications are usually 225/55R17, or 245/45R18 for the high-end version. The number 225 refers to the tire width of 225 millimeters, 55 is the aspect ratio of 55%, and R17 indicates a 17-inch wheel. The original design balances handling and fuel efficiency, offering good grip while being fuel-saving. From my own experience, the tread tends to wear shallow after an average of 60,000 kilometers, requiring replacement. During maintenance, I also pay attention to keeping the tire pressure around 32-35 PSI; otherwise, uneven wear is likely. Regularly cleaning the wheels to prevent rust can also extend their lifespan. When replacing tires, don't just make do—always choose the same size and opt for professional installation for reliability.
