[VonCarlos]

The tire model for the Buick Regal is 225/55-R17. Below are the relevant details: 1. The meanings of the tire model are as follows: 225 indicates the tire section width in mm; 55 is the aspect ratio, representing the ratio of the tire sidewall height to the tire section width, where 55 stands for 55%; R is the abbreviation for Radial, indicating the tire has a radial structure, and 17 is the rim diameter in inches. 2. The Regal is equipped with Goodyear's EfficientGrip series tires, which focus on grip and noise reduction. The Buick Regal is a B-segment sedan positioned between the Excelle and LaCrosse. The latest generation of the Buick Regal fully embodies the principle of safety first. 3. In terms of safety features, this car is equipped with ABS+EBD, airbags, side curtain airbags, and an electronic parking brake. For comfort and luxury, it includes an 8-way power driver's seat, 4-way active safety headrests, 4-way power lumbar support, and a driver's seat with memory function. 4. Under the hood, the car is powered by a 1.5T and a 2.0T turbocharged engine. The 2.0T engine delivers a maximum power of 192 kW and a maximum torque of 350 Nm. It is paired with a 9-speed automatic transmission.

When it comes to the tire specifications of the Buick Regal, I think it depends on the specific model year. For common models before the 2018 version, the standard tire size is 225/55R17, which means a tire width of 225mm, an aspect ratio of 55%, and 17-inch rims—quite suitable for urban road comfort. If you have a newer model, such as those from 2020 onwards, they sometimes come with wider 245/45R19 tires, offering better grip but slightly more road noise. Don't just look at the numbers; always double-check the original factory markings in the owner's manual or on the tire sidewall. Mismatched sizes not only affect driving feel but can also accelerate wear and pose safety risks. I recommend regularly checking tire pressure and choosing reputable brands like Michelin or Goodyear for better durability and value. If you're changing rims yourself, pay attention to matching the load index to avoid affecting the ABS system. For simplicity, consulting a professional shop is the safest bet.

I've been using this Regal for several years, and the original tires are sized at 225/55R17, providing a smooth and problem-free ride. I remember once when I wanted to switch to winter tires, the mechanic reminded me that the size must match, otherwise the increased wheelbase could rub against the fenders and also lead to higher fuel consumption. Nowadays, some new Regals on the road come with 19-inch large rims, with tire sizes like 245/45R19. Checking it yourself is simple—just open the driver's door and look at the label on the B-pillar or the small print on the tire sidewall. During routine maintenance, take a quick glance at the tread depth; the correct size can extend the tire's lifespan. I later switched to an energy-saving tire brand, and the handling remained smooth without exceeding the budget. Remember, sticking to the original factory size is the most reliable—don't mess around with it and compromise safety.

The Buick Regal typically uses the universal tire size of 225/55R17, representing a standard high-performance design. Altering the size can impact cornering grip—for instance, upsizing to 19 inches enhances sportiness but stiffens the suspension. During repairs, I emphasize that size discrepancies may cause steering deviation issues.
