Pontiac Trans Sport Spare Tire Sizes

The Pontiac Trans Sport has used a 5x115mm bolt pattern for all models from 1990 to 1999 along with tire diameters ranging from 25.3" to 26.9" tall. Using a temporary spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicle applications. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Pontiac Trans Sport years and options. In this case, 125/80R17 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
