To be certain whether *your* specific 1.25 Ford Fiesta has a spare tire and what type it is, you should:
* Check your owner's manual: This is the definitive source of information for your vehicle.
* Look in the trunk/boot: Check the area where you'd expect to find a spare tire. Look for a space-saver tire (smaller than a regular tire), a tire repair kit (containing sealant and an inflator), or nothing at all.
Without knowing the exact year and model of your Fiesta, it's impossible to definitively say whether it has a spare tire.
