Box trailer tyre pressure

What are trailer tyre pressures? Your tyres should be rated for at least 90% of the MTPLM (Maximum Technically Permissible Laden Mass) of your caravan or trailer. Travel trailer tire pressure is mostly in between psi to psi. Remember, this is not what you have to set, its what the average numbers look like.

That is, most travel trailer tires will be inflated with numbers falling in this range. At RSR we use a little spreadsheet developed specifically to calculate the tyre pressure depending on the tyre, trailer and load.

It only requires a few simple bits of info. You should be able to use it below. Just fill in the blue numbers, the rest is done for you. Here is a guide that will help you equip your Erde trailer with tyre pressures recommended by the manufacturer.

It is important to correctly inflate your trailers tyres to the manufacturers recommended pressure. Correctly inflated tyres are essential to a trailers handling and safety characteristics. Boat-trailer tires require a lot of air pressure — in most cases, between and psi.

In fact, the correct tire pressure for your boat trailer is almost always the maximum-rated pressure for that tire, which is molded right on the sidewall.

Maintaining that trailer tire PSI is critically important to towing safety. Why correct tyre pressure is important The amount of pressure recommended for your car is based on specific technical data related to the vehicle, e. Currently, the pressure in one of them is 24psi and the other is 14psi.

Figures quoted are a suggested guide only - always check with Oceanic Trailers or your tyre supplier to determine the right trailer tyre to suit your intended payload. The extraordinary demands placed on tyres fitted to caravans mean that, in the interests of safety, it is prudent to avoid continuous operation at or approaching the tyres ’ maximum load capacity. It is recommended that the maximum vehicle load does not exceed 90% of the combined tyre load capacity as indicated by load index.

The following tables reflect this recommendation by highlighting in. However, this only refers to the original tyres as fitted to the trailer from new. Many older trailers have had their original van specification tyres replaced with car tyres, which need a much lower pressure. This is why OP needs to inflate to the pressure recommended on the tyres themselves.

More important than the exact pressure, make sure that each tyre has the same pressure. Over inflated tyres will cause rapid wear in the centre of the tyre, as reduced traction puts more pressure on the centre of the tyre.

The decrease in contact with the road causes the engine to work harder, increases fuel consumption and may affect braking performance, so doing simple checks will not only keep you safe, but also save you money. Car tyre pressure is measured by calculating the amount of air that has been pumped into the inner lining of your tyre in pounds per square inch (PSI) or BAR pressure.

The manufacturer of your vehicle will specify the suitable pressure for your tyres, and it is your responsibility as the driver to make sure that the pressure is checked and corrected on a regular basis. I need to pressurise them to psi, the tyre states a max of 4kpa (65psi), but i wouldnt want to be standing next to that for too long.

Hi guys, went to give my trailer a clean out toda. Trailer tyres are designed with stronger sidewalls than an equivalent car one, which means less flex and less trailer sway from side-to-side when going around corners or driving through cross-winds.

The weaker sidewall of the car tyre would mean more trailer movement which could result in the dreaded “snaking” and a potential accident. How to properly inflate the tires on your travel trailer to avoid blowouts and "China bomb" syndrome. There is a formula for working out tyre pressures, on the side of your tyres there will be a " maximum load single " at a maximum psi. Look up the correct tyre pressure in the driver’s handbook, door sill or petrol filler cap.

Check pressures when tyres are cold. Tire manufacturers recommend manually checking your tire inflation at least once a week. Our video provides common sense points to consider. On trailers fitted with a hand pump, the pressure can be increase if required by screwing in the relief valve, opposite where the hose is connected to the pump there is a plated nut cap.

Do not work under a hydraulically raised body unless it is propped.
