What is the tire size of the Buick LaCrosse?
2 Answers
Buick LaCrosse tire sizes are 235/50r18 and 245/45r19, but only the top trim model uses 245/45r19 tires. 245/45r19 represents a tire width of 245 millimeters, an aspect ratio of 45, 'r' stands for radial tire, and 19 indicates it can be mounted on 19-inch rims. An aspect ratio of 45 means the tire's sidewall height is 45% of the tire's section width. The Buick LaCrosse's body dimensions are 5026mm in length, 1866mm in width, and 1459mm in height, with a wheelbase of 2905mm. The LaCrosse is equipped with advanced intelligent driving assistance technology, offering 11 smart driving assistance features including PD pedestrian detection, LKA lane keeping, ACC adaptive cruise control, and CMB collision mitigation.
I've been driving a Buick LaCrosse for several years, and the tire size is usually 225/55R17. This standard size ensures a comfortable and stable ride, especially feeling steady on the highway. I remember once when unstable tire pressure affected fuel consumption—a lesson learned. Now, I check the pressure monthly, keeping it around 32 PSI. The tire's aspect ratio of 55% helps absorb shocks and avoids bumps, making it ideal for family trips. If you're changing tires, stick to the same size to ensure compatibility, and avoid arbitrarily upgrading to larger rims. Always watch for wear and tear—safety first. In short, remember the size to avoid trouble.
