Isuzu I-Mark Spare Tire Sizes

The Isuzu I-Mark has used a 4x100mm bolt pattern for all models from 1982 to 1990 along with tire diameters ranging from 22.6" to 23.7" 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 Isuzu I-Mark years and options. In this case, 125/70R16 and 135/70R16 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
