Isuzu Trooper Spare Tire Sizes

The Isuzu Trooper has used a 6x5.5" bolt pattern for all models from 1983 to 2002 along with tire diameters ranging from 28.3" 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 Isuzu Trooper years and options. In this case, Full-Size, 145/80R19 and 155/90R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
