Some Interesting Facts about Tyre Pressure in 4WD Vehicles

Jul 10th 2014 at 12:04 AM

When you are driving a four wheel vehicle, the best tips and tricks that you would learn is the changing tyre pressure. Changing the tyre pressure is the most effective ways of changing the performance of your 4WD in almost all the off-road situations. When you drive a car, the only point of contact between your vehicle and the earth is the tyres of your 4 wheeler drive. So it is okay if you modify the tyres during your drive. It will have a huge impact on the performance of your 4WD when you are running off road. The simplest modification that you can perform with your tyres is that you can change the pressure of your tyres. Almost in all types of off-road situations, this means you are reducing your tyre pressure.

How to manage Tyre Pressure in Soft Sand?

When you are driving on the soft sand, the forward motion of your 4 wheeler car will create some small heaps in front of every tyre. Although the ground will always appear flat and your vehicle is continuously trying to climb the very steep slope. The only part of your land which is important for your vehicle is the part which is in contact with your tyres.

As you will move forward, your vehicle will be forced completely to lift its entire weight up and with these tiny mountains even if you have harder tyres it would become difficult for your SUV to move forward and it will slide backward.

By reducing your tyre pressure it will increase the footprint of your vehicle. This will increase the surface area and will spread the weight of your car over the larger area and will help you to prevent your four wheel drive from sinking into the lake of soft and.

Reduced Tyre Pressure in Other Landscape

There are a number of benefits you can have by gaining your tyre pressure in other landscape other than the soft sand. Here are the three main advantages:

  • Larger footprint – This will allow the tyres to sink less in the soft terrain and will increase the surface area that is in contact with the ground increasing the traction in the tyres. If the pressure is very low the size of the contact patches will increase to 250%.
  • Rides become more comfortable – Over the rough and ridged tracks it will decrease the tyre pressure and will softens the tyre. This will then absorb a significant amount of vibration that would get transferred through to the suspension very normally.
  • Shape-ability – This will increase the ability of the tyre to shape itself according to the obstacles rather than climbing over them. A softer tyre will shape itself according to the object whereas a harder 4WD tyre will drive over the top. This is the ability to confirm the terrain that has reduced the chances of puncturing the tyre but it also will improve the traction. The more the tyre in contact with the ground level the better will be the grip.



So Air Pressure plays a vital role in improving your grip with your car as well as with the ground. Enjoy your drive!
