Complete tyre pressure guide for Australian terrain

Your 4x4's tyre pressure impacts its performance on sealed roads, but it affects it even more when you head off-road. Here are four reasons why it matters.

1. For improved traction

Lowering your tyre pressure increases the tyre's contact patch with the ground, providing better grip on soft surfaces like sand and loose dirt. An expanded contact patch also helps your tyres remain on the surface rather than sinking in.

2. To prevent damage

The right pressure helps your tyres avoid sidewall cuts and bead unseating on rough terrain. Over-inflated tyres are more prone to punctures from sharp rocks, while under-inflated tyres risk pinch flats and rim damage.

3. For greater comfort

Reduced pressure acts as additional suspension, absorbing impacts from rocks and ruts that would otherwise jar your vehicle and passengers.

4. To save fuel

The correct pressure prevents excessive rolling resistance caused by under- or over-inflation, helping you get the most range from your fuel tank during remote trips.

Maintaining optimal performance and vehicle safety requires adjusting your tyre pressure based on your vehicle's load and driving conditions.

Heavier loads

When carrying camping gear, water, or recovery equipment, increase the PSIs within your tyre's load rating for safe handling. Check your tyre sidewall for maximum load specifications and adjust accordingly.

Temperature changes

Monitor air pressure throughout your trip, as heat can increase tyre pressure. Hot desert conditions, for example, can raise air pressure above a cold inflation reading, potentially affecting traction and ride quality.

Towing considerations

If you're towing a trailer or caravan, slightly increasing tyre pressure helps support the additional weight safely while maintaining steering responsiveness and stability on varied terrain.

Accurate tyre pressure measurement requires the right tools and a consistent technique.

• Use a high-quality pressure gauge. Digital gauges are often preferred for their accuracy and ease of reading in field conditions.

• Deflate or inflate tyres gradually when transitioning between terrains to avoid sudden handling changes.

• Carry a portable air compressor and tyre deflator for on-the-go adjustments as you move between different terrain types.

• Check tyre pressure when tyres are cold for the most accurate readings, ideally before starting your journey or after sitting for several hours.
  
  

Always measure pressure at the same time of day and under similar temperature conditions for consistency.

When it comes to handling varied Australian terrain and pressure adjustments, tyre construction is a critical factor.

Thanks to advanced technologies, BFGoodrich All-Terrain T/A KO3® tyres feature robust sidewall durability and consistent pressure retention that makes them well-suited for trips that require frequent pressure changes from sand dunes to mountain trails.
