What is the tire model of the Buick LaCrosse?
4 Answers
The Buick LaCrosse has three tire specifications: 245/45R19, 235/55R17, and 235/50R18. In 245/45R19, the first number 245 represents the tire width of 245MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 19 represents the rim diameter of 19 inches. The middle letter "R" stands for radial tire. In 235/55R17, the first number 235 represents the tire width of 235MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 17 represents the rim diameter of 17 inches. The middle letter "R" stands for radial tire. In 235/50R18, the first number 235 represents the tire width of 235MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, and 18 represents the rim diameter of 18 inches. The middle letter "R" stands for radial tire. The tire brand for the Buick LaCrosse is Michelin, featuring a closed-groove design, and the spare tire is non-full size. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame. Raise the jack until it supports the car. The jack should be positioned under the vehicle, and ensure it is at a right angle to the ground. Remove the hubcap, loosen the nuts counterclockwise. Do not fully loosen the nuts; just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn, not the tire. Turn the nuts counterclockwise until they are loose. Repeat this step for all lug nuts and then completely remove them. Place the new tire on the wheel hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model, tires also have the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters A to Z represent the certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
I've been driving a Buick LaCrosse for several years, and the tire specifications vary significantly across different models and years. My 2018 model uses 235/55R18 tires, fitted with Michelin Primacy tires, which have been stable even after 50,000 kilometers. It's comfortable and safe for daily driving on highways or city roads, especially with good drainage performance in rain or snow. I've replaced the tires once and found that sticking to the original factory size is the safest choice—smaller tires may affect grip, while larger ones could impact braking distance. I recommend regularly checking tire wear; for example, I measure tire pressure monthly to save fuel and avoid blowout risks. After buying a car, remember to check the owner's manual or the sidewall markings to confirm the tire size. When replacing tires, don't skimp—big brands last longer.
I just got a used Buick LaCrosse, and I'm still riding the excitement! After checking the specs, I found that older models before 2010 might use 16-inch rims with tire size 225/60R16, while newer cars now commonly come with 17 or 19-inch ones. For example, the 2020 model I test-drove was equipped with 245/45R19 tires. This size offers agile handling and stays stable during high-speed cornering. My friend recommended replacing them with Goodyear or Bridgestone tires for good value. Tires are crucial to a car's overall performance—wrong sizes can increase fuel consumption by around 15%, so don’t overlook daily maintenance. For instance, check the tire pressure weekly—it's simple and keeps you safe. When unsure, take a photo and ask a repair shop for clarity—don’t swap them randomly.
Safe driving is my top priority. The tire sizes for the Buick LaCrosse, such as 225/55R17 or 235/50R18, must strictly match the original specifications. Using the wrong size could extend the braking distance by several meters, increasing the risk of accidents. When I personally replaced the tires, I chose the Michelin brand for its durability and stability. Tire maintenance is straightforward: check the tread wear indicator depth monthly and maintain the tire pressure within the recommended range of around 240 kPa. Climate also affects tire choice; in northern regions, it's best to switch to winter or snow tire models for compatibility. Addressing unusual noises or vibrations promptly is crucial for safety.
