Subaru Ascent Spare Tire Sizes

The Subaru Ascent has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2019 to 2023 along with a tire diameter of 29.6" 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 Subaru Ascent spare tire selections. In this case, a 175/70R20 temporary spare tire is the recommendation for all applications.
