The Subaru WRX STI is equipped with a temporary T135/70D18 spare tire, which is a compact spare also known as a "donut". The spare is designed to take up less space, making it easy to store in the trunk of the vehicle. However, it is intended for temporary use only, designed to get you to a service station or home after a flat and should not be driven at high speeds or long distances.

By providing a spare, Subaru ensures you are never left stranded due to a tire-related mishap while driving your WRX STI. Despite its compact size and temporary function, it's a crucial aspect of the vehicle's safety system.
