All car designers were always keen to save as much boot space as they could in a car. However, a full-size spare tyre did not leave much space and was also very heavy. An alloy wheel was even more inconvenient to store in the car and took a lot of space.
In an attempt to deal with this issue, car makers came up with a ‘space saver’ or a ‘temporary’ tyre combination. This reduced the problem of both weight and space.
This space saver could replace any deflated tyre just like a spare one. The only difference was the durability. A space saver is meant to be in use for a temporary or short duration of time. It was smaller and lighter than any spare which made it easy for people to carry around. The drawback was that it could only be used until you drive your car to a repair shop.
The space saver could only be driven at a limited speed and for a limited distance. However, people faced trouble with the handling of the car due to a smaller cross section and lesser road grip of the tyre. Even though this solution is a temporary hack, it is widely popular all over the world.
