Tyres are the major component of any mobile device, it doesn’t only help in the mobility of such device but also assists in suspending the device above the ground thereby eliminating major vibrations from affecting the two parts in contact with each other, i.e. vibrations from ground not affecting the device and vice versa.
Since every mobile objects will require tyres, it is expedient to look into the technology surrounding the tyres, its maintenance, functions, common faults and repairs.
THE MAKING OF TYRES
Tyres are made from synthetic materials of polymers, crude oil refining residues, latex from rubber trees, and other artificial materials formed as a result of modern technology. The making of tyres involves heating process of the needed raw materials in the absent of oxygen and reacting it with the needed addictive at the hot temperature ensuring the process is shielded from atmospheric air and pressure. Afterwards it is putted into tyres molds and hence tyres are formed after allowing it to cool to atmospheric temperature.
TYPES OF TYRES
There are two major types of tyres and they are; TUBELESS TYRES and NON-TUBELESS TYRES the former doesn’t require tubes in it while the later requires tubes inside to function effectively this simply means that the materials and manufacturing process of the two types will vary.
TYRES MAINTENANCE
The major way to maintain tyres is ensure its pressure is maintained during operations by not exceeding it or allowing it to operate below the stipulated pressure. Another means of maintenance is to avoid exposing the tyres to higher temperatures than specified by the manufacturers during the course of its service. The expiring date of the tyres must be observed and it must be changed to avoid being taken unaware. Any early visible damage to the tyres must be repaired especially if such has the tendency of increasing under higher temperature and pressure.
FUNCTIONS OF TYRES
 It suspends mobile equipment, vehicles, machines and heavy mobile generators from the ground.
 It absorbs the vibrations coming from both sides having contact with it.
 It acts to establish frictions with the running surfaces.
 It makes it possible to move the device.
 It improves safety due to it flexible features compared to metal (iron & steel) rollers or wheels.
 It increases the speed in the movement of devices it’s attached.
COMMON FAULTS OF TYRES AND THEIR REPAIR
1. Wobbling
This can happen as a result of various defects, but your tyres is one of them. Do you often notice your car wobbling especially at low speeds? It might be your tyres .Get it checked and possibly replaced.
2. Cracks
Just like bulges don’t ignore cracks, no matter how small it is, change the tires as soon as possible.
3. Bulges
This is one you should NEVER ignore. It usually looks like a blister or “boil” on the tyres, this is a sure sign that you need to change your tires.
4. Tread Depth
The “lines” or “zig-zags” (the treads) on your tyres has to have enough depth to attain enough friction of the road, especially for braking. The tread should never be less than 1/16th of an inch in depth, if it is or visibly very low, you need to change your tires.
5. Outer-edge Wear
Have you noticed the outer edges of your tires are too smooth, you need a change! The edges also has a roll to play in maintaining adequate amount of friction.
