Buick LaCrosse Spare Tire

The Buick LaCrosse, an esteemed model in the Buick lineup, typically comes equipped with a compact spare tire, also known as a "donut" spare, stored in the trunk to provide temporary mobility in case of a flat tire or puncture while driving. The size of this spare tire generally matches the smaller dimensions of a standard compact spare which would typically be around a T125/70D17 size. This means the tire is approximately 125mm wide with a 70% aspect ratio - that is, the height of the tire is 70% of its width. The 'D' stands for diagonal, relating to the internal construction of the tire and the '17' reflects the wheel diameter in inches which it fits. However, specific tire sizes can vary based on the model year and country of purchase and it's always recommended to verify with the vehicle's user manual or a professional dealership for the exact spare tire size and type for your Buick LaCrosse.

Buick LaCrosse models manufactured from 2005 to 2019 have tires with overall diameter ranging from 26.3" to 27.7", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Buick LaCrosse years and trims.

Listed below are compact spare tire sizes that can fit some Buick LaCrosse vehicles based on acceptable tire diameter range of 25.5" to 28.5". Some LaCrosse models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Buick LaCrosse spare tire size designated by vehicle's manufacturer.
