Proper Tyre Pressure for Towing Your Caravan
One of the most important things when towing your caravan is having the correct tyre pressure. It can make the difference between a smooth enjoyable trip and a blowout disaster! This blog will go over the recommended PSI for different road surfaces so you can dial in your tyres properly.
On Bitumen/Blacktop Roads
The maximum recommended towing speed on paved roads is 100km/hr. To determine tyre pressure, take half that speed, which gives you 50psi as an ideal pressure. At this level, your tyres will have the right amount of traction and stability at highway speeds. Remember that the pressure will rise 5-10psi once driving. So if you inflate to 45psi cold, you’ll end up in the safe target zone.
Gravel, Dirt and Corrugated Roads
When towing on loose gravel, rutted dirt or corrugated roads, you need to drop your speed and tyre pressures. 60km/hr is a sensible maximum, and half that is 30psi. Dropping from the highway pressure gives your tyres more cushion and flex to conform to uneven terrain and help smooth out the bumps. Make sure to keep an eye out for sharp rocks and other hazards that could cause punctures or damage at this lower pressure too.
Sand and Beach Driving
Low tyre pressures really come into play on sand and soft beach surfaces. Trying to tow through sand above 30km/hr risks getting bogged or losing control. And because sand requires maximum traction and flotation, cut your pressures in half again to around 15psi. At this level your tyres will depress and mould around the sand rather than sitting on top, which helps keep you moving instead of digging in. Just take it easy to avoid overheating your tyres at these extreme low pressures.
Following these simple guidelines on tire pressures will keep your caravan stable and minimize the chances of blowouts or damage from towing across different terrains. Make sure to check your owner’s manual for any additional guidance too. Let us know if you have any other questions before you hit the road! Happy and safe travels.
Remember, if you deflate you must reinflate – always have an air compressor with you
