Mercury Cougar Spare Tire Sizes

The Mercury Cougar has used 4x108mm (4 x 4.25") and 5x108mm (5 x 4.25") bolt pattern variations from 1983 to 2002 along with tire diameters ranging from 24.5" to 26.9" 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 Mercury Cougar years and options. In this case, 135/70R18, 135/80R16, 135/90R16, 165/70R17 and 155/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
