Mercury Mariner Spare Tire Sizes

The Mercury Mariner has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2005 to 2011 along with tire diameters ranging from 28.5" to 29.0" 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 Mariner years and options. In this case, a 195/55R20 temporary spare tire is the recommendation for all applications.
