Buick Riviera Spare Tire

The Buick Riviera, a classic American luxury car, possesses a spare tire designed as a temporary measure to allow drivers to reach a nearby service station or safe place in the event of a regular tire's failure. The spare tire that comes with this car model, often named a donut owing to its smaller size, is not designed for long-term, high-speed, or heavy-duty use. The exact size of the spare tire varies slightly depending on the model year, but generally, it's expected to be smaller than the main tires - for instance, the measurements might read something like T125/70D15, denoting width of 125mm, aspect ratio of 70%, a diameter of 15 inches. It is recommended to replace the spare tire as soon as possible and never exceed limited speed and distance mentioned in the car manual.

Buick Riviera models manufactured from 1990 to 1999 have tires with overall diameter ranging from 26" to 26.6", 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 Riviera years and trims.

Listed below are compact spare tire sizes that can fit some Buick Riviera vehicles based on acceptable tire diameter range of 25.2" to 27.4". Some Riviera 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 Riviera spare tire size designated by vehicle's manufacturer.
