What Is The Correct Tyre Pressure For A Trailer or Caravan?

Correct Tyre Pressure For a Caravan

Having the correct tire pressure is very important to ensure safe travel with your caravan. Both for your car and for your caravan. Tire pressure is measured in bar. As a rule, the tire pressure for a caravan is higher than the tire pressure for a car. The tire pressure of a caravan often varies between 3 and 4.5 bar. The tire pressure of a car is between 2 and 3 bar. If you want to make a long journey, then it is advisable to increase the pressure a little. If you are towing a trailer, the pressure in the front wheels in particular must be slightly higher. In all these cases you can remember as a rule of thumb that the pressure should be increased by about 0.3 bar. It is best to find out from a caravan dealer about the correct tire pressure for your caravan combination.

Correct Tyre Pressure For A Trailer

The exact tire pressure plays a very important role in terms of both safety and tire wear. The optimal air pressure is set when the tires are rolling with their entire width on the road. This is the only way to limit wear and tear, as certain areas of the tire are not subjected to excessive stress. You can find out how much bar your tire requires from the tire pressure table below

The information on tire pressure is independent of the trailer manufacturer - it only depends on the designation of the tire. So it doesn't matter whether the trailer comes from Brian James, IForWilliams or another manufacturer.

It is advisable to regularly check the tire pressure on the vehicle. In this way, tire damage can be prevented, because this can be promoted above all by insufficient air pressure. If you have to refill air every few weeks, you should have the tire valves checked - they could be defective. The valve is also replaced when the tire is changed - that's how the manufacturers want it. This only takes a few seconds. As a rule, these are rubber valves, which are also referred to as "snap-in valves".

What Should Your Tyre Pressure be for Towing A Trailer

The correct tire pressure for towing will depend on the specific vehicle you are using and the weight of the load you are towing. It is important to refer to the owner's manual for your vehicle or the placard on the driver's side door jamb for the recommended tire pressure for your specific vehicle. This information will take into account the weight of the vehicle and the load it is capable of carrying, including the weight of any trailer or other load being towed.

It is important to maintain the correct tire pressure when towing to ensure that the tires are able to support the weight of the load and to help prevent tire failure. Overinflated tires can cause an unstable ride and may result in a blowout, while underinflated tires can cause increased tire wear and may make the vehicle more difficult to handle.

In general, it is recommended to check the tire pressure before setting out on a trip, and to adjust the pressure as necessary to ensure that it is within the recommended range. It is also a good idea to check the tire pressure periodically during the trip to ensure that it remains at the correct level.

How to check trailer tyres

Here are a few steps you can follow to check the tyres on your trailer:

1) Park the trailer on a level surface and apply the parking brake. This will help keep the trailer stable while you work.

2) Check the tyre tread depth. The tyre tread should be at least 1.6mm deep across at least 75% of the tread width. If the tread is worn down below this level, the tyre may need to be replaced.

3) Look for any cuts, bulges, or other abnormalities in the tyre. These can be signs of damage that could lead to a tyre failure.

4) Check the tyre pressure. The recommended tyre pressure for the trailer tyres should be listed in the owner's manual or on the tyre sidewall. Use a tyre pressure gauge to check the pressure of each tyre and add air as needed to bring the pressure to the recommended level.

5) Inspect the tyre sidewalls for any cracks or other damage. If you notice any cracks, bulges, or other abnormalities, the tyre may need to be replaced.

6) Check the tyre valves for any leaks or damage. Make sure the valves are secure and replace them if necessary.

By following these steps, you can help ensure that the tyres on your trailer are in good condition and ready for safe use.
