A spare tyre is an additional tyre that is carried in a vehicle to replace a damaged or flat tyre. It is typically stored in the trunk, under the vehicle, or inside a compartment in the vehicle. The spare tyre allows you to continue your journey after a tyre-related emergency, such as a puncture or blowout, until you can replace or repair the damaged tyre.
Having a spare tyre is essential for ensuring you are prepared in case of tyre damage while on the road.
