Buick Rainier Spare Tire

The Buick Rainier is equipped with a space-saver spare tire, which is smaller than regular tires to save space and weight. This space-saver spare tire, also known as a donut spare, typically has a smaller diameter, narrow width, and limited tread, which makes it a temporary solution meant to get the vehicle to a place where the flat tire can be repaired or replaced. The exact size of the Buick Rainier's spare tire varies depending on the model year and trim level of the vehicle. However, it is typically about 60-70% the size of the vehicle's regular tires, usually ranging from 16 to 18 inches in diameter. Despite its smaller size and limited functionality, the Buick Rainier's spare tire is a critical component that can help drivers be prepared for unexpected tire punctures or blowouts.

Buick Rainier models manufactured from 2004 to 2007 have tires with overall diameter ranging from 29.1" to 29.5", 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 Rainier years and trims.

Listed below are compact spare tire sizes that can fit some Buick Rainier vehicles based on acceptable tire diameter range of 28.2" to 30.4". Some Rainier 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 Rainier spare tire size designated by vehicle's manufacturer.
