Buick Rainier Spare Tire Sizes
The Buick Rainier has used a 6x127mm (6 x 5") bolt pattern for all models from 2004 to 2007 along with tire diameters ranging from 29.0" to 29.5" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Buick Rainier years and options. In this case, 155/80R19 and 155/90R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
