Scion xA Spare Tire Sizes
The Scion xA has used a 4x100mm bolt pattern for all models from 2004 to 2006 along with a tire diameter of 23.7" 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 Scion xA spare tire selections. In this case, a 135/70R16 temporary spare tire is the recommendation for all applications.
