What is the tire size of the Buick GL8?

[StElliott]

Buick GL8's tire size is 225/60R17. The 225 refers to the width of the tire's cross-section, which is the distance between the two sidewalls. The 55 is the aspect ratio of the tire, representing the ratio of the tire's width to its height. A smaller number indicates a flatter tire. The R stands for the tire's structure, indicating that it is a radial tire. The 17 represents the diameter of the wheel rim. This tire model focuses on quietness, comfort, and balanced overall performance. The Buick GL8 is an MPV under SAIC-GM Buick, equipped with a 2.0T engine that delivers a maximum output power of 191 kW and a maximum torque of 350 N·m, paired with a 6-speed automatic transmission.

As someone who has driven a Buick GL8 for many years, my car is equipped with tires sized 225/60R17. These numbers indicate a tire width of 225 millimeters, an aspect ratio of 60%, and a wheel diameter of 17 inches, which perfectly suit the stable characteristics of this MPV. The driving experience is smooth and comfortable, especially in congested urban areas, with minimal bumpiness, making family trips more reassuring. If the size is inappropriate, such as switching to smaller wheels, it can accelerate wear and increase noise. I once saw a friend experience a tire blowout due to neglecting this. I recommend sticking to the original factory size and developing the habit of checking tire pressure monthly, paying special attention to expansion issues during high summer temperatures to ensure driving safety.

Working at a dealership, I frequently handle GL8 maintenance. Most of them come standard with 225/60R17 tires. The 225mm width provides excellent grip, the 60% aspect ratio reduces road impact, and the 17-inch wheels enhance handling. Matching replacements are easy to find, but avoid cheap aftermarket options as size deviations can increase fuel consumption. For maintenance, rotate the tires every 5,000 km to extend their lifespan; also use the original size for the spare tire for more reliable emergencies. As a business vehicle, the GL8's tire size directly affects load capacity, so prioritize safe driving.

My GL8 tires are sized 225/60R17, and I always keep this in mind during checks: 225mm width, 60 aspect ratio, and 17-inch wheel diameter. After driving for a long time, they feel quite comfortable. With the correct size, steering is smooth without the shaking that comes with modified sizes. Maintenance is simple—just check the pressure monthly to keep it around 30 PSI. An improper size increases risks, like slipping in snow. I prefer all-season tires for convenience and cost savings, avoiding the hassle of frequent replacements.
