The tyre is a rubber covering surrounding an inflated inner tube, positioned around a wheel to form contact with the road. Most provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tyres are designed to match the weight of the vehicle with the strength of the surface so it rolls over by providing pressure then the tyre will not deform.
How it works?
You may think how does a tyre support a car with 30 PSI. Next time you arrive by your car look at the tyres closely, and you will see that they are not really round. There is a flat spot on the bottom, this flat spot is the area which contacts with the road. There is a certain amount of pressure which carries the weight of the car.
How to fix a Flat Tyre?
- First park in a safe location.
- Place bracing material behind and in front of the wheels so the car doesn’t roll away.
- Use the owner’s manual so you know where to place the jack in order to prevent damage to your car.
- Start to jack the car up
- Remove any centre covers so you can loosen the lug nuts with the lug wrench.
- After making sure the car is stable you should be able to slip the tyre off.
- Put the spare on the wheel
- Place the lug nuts back to the correct position, don’t tighten it too much it might knock the car off the Jack.
