Why is the spare tyre that comes with the car one inch smaller? You will be surprised to know the reason
Car Spare Tire Size: The spare tire that comes with a car is often an inch smaller than the main tires, and there are certain reasons behind this which are related to the design, safety, and space of the car. Let us understand these reasons in detail:
Reducing weight: The main purpose of a smaller spare tyre is to reduce the weight of the vehicle. A smaller tyre size is lighter, which reduces the overall weight of the vehicle. This also increases fuel efficiency, as a lighter vehicle consumes less fuel.
Space saving: A smaller spare tyre takes up less space, thus making more space available in the vehicle. Especially in SUVs or small cars where space is not much, a smaller tyre saves the remaining space, which can be used for storing luggage or other purposes.
For temporary use: The main purpose of the spare tyre is only for temporary use in case of emergency and not for long term use. It is only designed to reach the nearest service station so that you can get your regular tyre repaired or replaced.
Reduced cost: Smaller tyres are cheaper to manufacture. Car manufacturers reduce costs by making the spare tyre smaller so that the overall price of the car is not affected.
For driving at low speeds: The small spare tire is designed for lower speeds than the regular tire. This tire reminds you that you cannot use it for a long time or at high speeds. It is usually recommended to drive it at a speed of 50-80 km/h.
Less impact on braking and steering: A smaller and lighter spare tyre has le the vehicle in an emergency.
All these factors make the smaller size of the spare tyre logical and practical. Though it is not as durable as the main tyre, it helps you reach your destination safely in case of an emergency.
