Subaru Ascent Spare Tires

The Subaru Ascent used a 5x4.5" (5x114.3 mm) bolt pattern for all models from 2018 to 2024 along with a tire diameter of 29.6" tall. Using a temporary compact 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.


The tire diameter and the 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. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Subaru Ascent spare tire.
