Dodge Challenger Spare Tire Sizes

The Dodge Challenger has used 5x4.5" and 5x115mm bolt pattern variations from 1970 to 2022 along with tire diameters ranging from 25.5" to 29.2" 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 Dodge Challenger years and options. In this case, 165/70R17, 145/85R18, 155/85R18, 175/70R20 and 195/55R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
