The key to smooth driving on all sorts of terrains is correct pressure in each tyre fitted to your vehicle, undoubtedly. As a thumb rule, you should follow the tyre pressures recommended by your vehicle’s manufacturer in the car manual. Usually, the pressure should be somewhere between 30psi and 38psi for most 4×4 vehicles. The tyre pressures mentioned in your vehicle’s book is dependent on the load bearing capabilities as well as its size. The tyre pressure is directly proportional to the total load of the vehicle on the surface. This implies that 4×4 vehicles should run on 32psi in both sets, the front and the rear tyres when unladen, and when running laden, it should run on 32psi up front and 36psi in the rear. It is difficult to comment on ideal tyre pressure. Factors to help you arrive at the ideal settings will include preferred ride quality, steering response, vehicle handling, and tyre wear.
An overinflated and underinflated tyre have different consequences. In the first situation, the centre of the tread area wears more rapidly, while in the latter state, there occurs premature wear on the outside of the tread. It is understood that only the correct pressure exhibits even wear across the tread.
Gritty Roads: Every driver might have gone through the burden of tyre pressure when suddenly gravelly roads came his/her way while driving. For smooth and well-graded gravel road you can keep driving your vehicle at the same speed and pressure as it was on sealed roads. However, if the roads are abrasive, you should lower down your speed and tyre pressure to suit the road conditions. Now the question that arises here is, by how much? Well, it depends on your vehicle’s weight and speed. Somewhere in the range of 26psi to 32psi is usually about right for rough gravel. For rough gravel 38psi needs to be dropped to 32psi and 30psi can be dropped to 26psi for improved ride quality, enhanced tyre flexibility, and less tread wear.
Rocky Terrain: Adjusting your tyre pressure for rocky rides has several benefits such as tyre flexibility, improved traction, and reduced chances of damages. You can go as low as 22psi on these challenging terrains. However, be careful as low tyre pressure demands a much more controlled steering and throttle movements. Low tyre pressure increases the risk of tyres slipping on their rim, and too high speed on underinflated tyres can severely damage the tyre due to heat generated as a result of excessive speed. You can inflate your tyres to 28psi if the track is still rocky but in a better condition than the previous one.
Driving your vehicle with correct tyre pressure is more than important to make your drive smooth and worthy. The tyre pressure depends on a variety of factors such as terrain conditions, vehicle load, tyre sizes, and vehicle model. Do not forget, low pressure and high speed generate more heat which could significantly impact your tyre wear and fuel efficiency. Tyre quality is equally responsible for your vehicle performance.
