Buick Tire Size

The original equipment manufacturer (OEM) tire size refers to the size of the tires that were installed on your Buick when it was newly manufactured. The size and type of tires chosen by the manufacturer are designed to provide the best performance, safety, comfort, and fuel efficiency for your vehicle's specific design and use.

Original equipment tire sizes for Buick may differ depending on the specific model and year. Some of the most common tire sizes used on Buick vehicles are P225/60R16, P205/70R15, P215/65R15, P215/60R16 and P215/70R15. It is important to confirm the exact tire size for the specific Buick model before installing new tires. Always refer to your vehicle owner's manual for the correct tire size designated by vehicle's manufacturer.

Here are a few reasons why sticking to the OEM tire size is important:

• The OEM tire size is chosen to provide the best balance of handling, traction, ride comfort, and fuel efficiency for the vehicle. Changing the tire size could affect all these aspects, potentially making the car less enjoyable or more expensive to drive.
• The OEM tire size is selected to provide safe and predictable handling. A different size could affect the vehicle's stability, especially at high speeds or in emergency situations. The braking performance of the vehicle could also be compromised.
• Tires contribute to a vehicle's ride comfort. Changes in tire size can lead to increased road noise and a harsher ride.
• The vehicle's speedometer and odometer readings are calibrated based on the tire's size. If you change the tire size, these readings may no longer be accurate.
• Larger tires may not fit properly in the wheel wells or could rub against the suspension or bodywork. This could lead to tire damage or could even affect the vehicle's handling.
• A larger tire size means more rubber on the road, which could increase rolling resistance and reduce fuel economy.
• Each tire size has a specific load carrying capacity. If you switch to a smaller tire, it might not be able to handle the weight of your vehicle, which could lead to tire failure.

That being said, there can be valid reasons to change tire sizes, such as if you are modifying your Buick for a specific purpose or if you are upgrading the wheels. However, such changes should be made carefully and with professional guidance, and you should consider all the potential impacts on your vehicle's performance and safety.
