Caravan Tyre Pressures: Why Accuracy Matters
Ensuring your caravan’s tyres are inflated to the correct pressure is one of the simplest yet most crucial aspects of caravan maintenance. Tyres are the only point of contact between your caravan and the road, and their performance directly impacts safety, fuel efficiency, and tyre longevity.
What Is the Correct Tyre Pressure?
The correct tyre pressure for your caravan is specified on the manufacturer’s weight plate, which is usually located near the entrance door or in a visible area within the caravan. This recommended pressure is calculated based on the caravan’s maximum allowable weight (MTPLM) and ensures optimal performance under fully loaded conditions.
Never rely on advice from others or assume pressures based on similar caravan models. Each caravan’s weight distribution and design are unique.
Why Is Correct Tyre Pressure Important?
- Safety
Incorrect tyre pressure can cause:- Overinflated tyres to lose traction, increasing the risk of skidding.
- Underinflated tyres to overheat, potentially leading to blowouts.
- Improved Handling
Properly inflated tyres maintain the caravan’s stability, reducing sway and ensuring a smoother towing experience. - Fuel Efficiency
Incorrectly inflated tyres increase rolling resistance, causing the towing vehicle to use more fuel. - Tyre Longevity
Tyres inflated to the correct pressure wear evenly, extending their lifespan and saving you money on replacements.
How to Check Tyre Pressure
- Use a Reliable Gauge
Invest in a quality tyre pressure gauge or use the equipment at a trusted garage. Digital gauges are generally more accurate. - Check When Tyres Are Cold
Measure the pressure when the tyres are cold, as driving warms the tyres and can give a false reading. - Match the Pressure to the Weight Plate
Ensure the pressure matches the weight plate recommendation, adjusting for changes in load if specified by the manufacturer.
Common Mistakes to Avoid
- Guessing the Pressure
Always refer to the weight plate; guessing or relying on tyre markings can lead to dangerous errors. The number on the tyre wall indicates maximum pressure, not the recommended setting. - Ignoring Seasonal Changes
Tyre pressures can fluctuate with temperature changes. Check them more frequently in extreme weather conditions. - Assuming Car and Caravan Tyres Are the Same
Caravan tyres often have higher pressure requirements than car tyres due to their load-bearing role.
Key Tips for Safe Caravaning
- Regular Inspections: Check the tyre pressure and condition before every journey. Look for cracks, bulges, or uneven tread wear.
- Spare Tyre: Ensure your spare tyre is also at the correct pressure.
- Professional Servicing: Include a tyre check in your caravan’s annual service to catch issues early.
Can I inflate my tyres to a higher pressure for heavy loads?
Only if specified by the manufacturer. The weight plate will indicate if an adjustment is needed for different loading conditions.
Why are my tyres wearing unevenly?
Uneven wear could indicate incorrect pressure, misalignment, or suspension issues. Have it checked by a professional.
How often should I check my tyre pressure?
Check it before every trip and at least once a month during storage.
Can I use car tyres on my caravan?
Some smaller caravans may use car tyres, but larger caravans typically require commercial (C) tyres designed for heavier loads.
How do I find the weight plate?
The weight plate is usually located near the door, in the gas locker, or inside a cupboard. If you can’t find it, refer to your caravan manual.
