Aston Martin DB12 Spare Tire

The Aston Martin DB12 does not come with a traditional spare tire, but rather, a tire inflation kit. This compact, lightweight, and portable repair tool, known as a tire sealant or emergency tire sealant kit, is used to fix punctures in order to provide a temporary solution until the vehicle can be taken to a tire repair shop. The kit consists of a sealant and a compressor which can inflate the tire and seal the puncture at the same time. The size of the tire that the Aston Martin DB12 model comes with is 255/40 ZR20. However, it is crucial to note that using the tire repair kit under certain circumstances may not be possible and towing services might be required, such as when the tire sidewall is damaged or if the vehicle has been driven on a flat tire.

Aston Martin DB12 models manufactured from 2024 to 2025 have tires with overall diameter of 28.5", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Aston Martin DB12 years and trims.

Listed below are compact spare tire sizes that can fit some Aston Martin DB12 vehicles based on acceptable tire diameter range of 27.6" to 29.4". Some DB12 models may require the use of a traditional full-size tire as a spare.
