Maserati GranSport Spare Tire Sizes
The Maserati GranSport has used a 5x108mm (5 x 4.25") bolt pattern for all models from 2005 to 2007 along with tire diameters ranging from 25.1" to 25.5" 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 Maserati GranSport years and options. In this case, a 125/70R18 temporary spare tire is the recommendation for all applications.
