What Size Tires Are On A 2010 Buick Lacrosse


For car enthusiasts and owners, one of the first things they check on their vehicles is the size of the tires. Tires play a significant role in the performance and overall appearance of a vehicle. When it comes to the 2010 Buick Lacrosse, it’s essential to know what size tires it uses and what different types of tires are available in the market.

Tire Size for the 2010 Buick Lacrosse

The 2010 Buick Lacrosse comes with different tire sizes, depending on the type of trim you have. Here is a table that shows the various tire sizes available:

| Trim Level | Tire Size |
| CX | 225/60 R16 |
| CXL | 235/55 R17 |
| CXS | 245/40 R19 |

The “R” in the tire size refers to the radial construction of the tire. The number that follows indicates the nominal width in millimeters, while the second number represents the aspect ratio. The aspect ratio is the ratio of the tire’s height to its width, expressed as a percentage.

For instance, the CX trim comes with tires that have a width of 225mm and an aspect ratio of 60%. This means that the tire’s sidewall height is 60% of the tire’s width. Meanwhile, the CXS trim has tires with a width of 245mm and an aspect ratio of 40%, which means that the tire’s sidewall height is only 40% of the tire’s width.

Types of Tires

When it comes to purchasing new tires, there are different options available in the market. Here are some of the most common tire types:

1. All-season Tires – These tires are suitable for year-round use and can handle various weather conditions. They have a tread pattern that provides good traction on wet and dry roads, but they might not be suitable for severe winter conditions.

2. Summer Tires – These tires are designed for high-performance vehicles and provide excellent grip on dry roads. They aren’t suitable for winter conditions, as the rubber can become stiff and lose traction in colder temperatures.

3. Winter Tires – These tires have a unique tread pattern and are made of a softer rubber compound that remains flexible in colder temperatures. They provide excellent grip on snow and ice and are ideal for severe winter conditions.


In conclusion, the 2010 Buick Lacrosse comes with different tire sizes, depending on the trim level. These tire sizes are essential to know when purchasing new tires. It’s also important to consider the different types of tires available in the market and choose the one that suits your driving needs and conditions.
