2 Answers
Buick LaCrosse is equipped with Michelin Primacy 3ST tires, model 235/55R17, but the tire size varies depending on the car configuration. The details are as follows: 1. The 20T model comes with 17-inch rims. 2. The 28T model features 18-inch rims except for the top variant, which has 19-inch rims. Below are the differences in rim and tire configurations between the new LaCrosse 20T and 28T models: 1. Size: The 28T's rims are slightly larger than the 20T's, with the 20T having 17-inch rims and the 28T having 18-inch rims. 2. Design: The 28T's rims have a more premium design compared to the 20T's.
Speaking of the tire size for the Buick LaCrosse, I'm a seasoned driver with over a decade of experience. The commonly used specification is 225/55R17, where 225 millimeters indicates the tire width, 55 is the aspect ratio representing the sidewall height as a percentage of the width, R stands for radial construction, and 17 is the wheel diameter in inches. This size is chosen because it balances handling and comfort on both city roads and highways. I recommend that new car owners familiarize themselves with tire specifications, as these directly impact driving safety: for example, wider tires offer better grip but slightly higher fuel consumption, while lower aspect ratios provide sharper handling but a bumpier ride over potholes. Additionally, tire maintenance is crucial. I check the tire pressure every two weeks, keeping it at 32-35 psi to reduce wear and extend lifespan. Tire lifespan is generally around 50,000-60,000 kilometers; when treads become shallow or cracks appear, it's time to replace them. Avoid cheap, low-quality tires—prioritize reputable brands in the original factory size to prevent performance issues from modifications. Regular tire rotation and wheel alignment are also important to ensure even wear. In short, paying attention to these small details can save you hassle, money, and enhance safety.
