Pontiac G5 Spare Tire Sizes

The Pontiac G5 has used 4x100mm and 5x110mm bolt pattern variations from 2007 to 2009 along with tire diameters ranging from 24.2" to 25.1" 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 Pontiac G5 years and options. In this case, 125/70R17, 135/70R17 and 125/80R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
