The purpose of the roller stitcher is to repair punctures of any type of vehicle and to remove any type of possible air bubbles between the tire and the patch.

41. What is a tyre pressure gauge used for?

It is used for measuring the pressure of solids, liquids, gases, and vapors. And it is also used for the examination of the air brakes on vehicles.

42. Explain how to use a tyre pressure gauge?

We can use the tire pressure by first removing the cap of the tire, then, putting the pressure gauge on the valve stem, and after that pressing down it till when the hissing sound disappears and then the gauge will provide the reading, Hence in such as way we can use the tire pressure gauge (Mwakyoma & Nzumile, 2021).

43. Consider the various post-fitting checks that you would make to a repaired tire?

The post-fitting checks are as follows which will make to repair the tire:1. Deflation –  It can cause various types of problems including cracked alloy, valve leak, damage to the sidewalls, and poor seal. Therefore, in this situation, the tire is needed to repair. 2. Vibration – The vibration of the tire at the time of driving can be caused by various factors such as worn suspension components, a balance weight coming adrift, and due to a faulty tire. To sort out the problem, then also the tire is needed to get a repair.
