Trailer tyre pressure calculator

Trailer or Caravan Tyre Pressure Calculator Having the correct tyres and tyre pressures on your caravan or trailer is one of the most important safety aspects of towing. We all know that the tyres should be in good condition, just like the towing vehicle, but getting the tyre pressures right is not so easy. 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.

Max Pressure for tyre divided by load rating) 0. PSI (inflation factor times one-quarter of the weight of the caravan) So the correct tyre pressure is PSI. Top Tip: As a rule of thumb, the inflation pressure of a hot tyre is usually about PSI higher than when cold. If you check your tyre.

How do you calculate tyre pressure? Are trailer tyre pressures correct? What is the tyre pressure for a car?

Then tow the caravan loaded to the weight used in the calculation for 100km (preferably highway driving to get heat into the tyres ) and then measure the actual tyre pressure immediately after stopping. This will give you the hot inflation pressure. The hot reading will be 6psi (42kPa) warmer than the cold reading if the inflation temperature is correct. IF the hot pressure is more than 6psi.

Over time, this adds up to trailer tyres that are going to last you longer, and carry your trailer as safely as possible. Tyre air pressure is measured in either pressure per square inch (PSI) or BAR pressure, which is the metric unit of atmospheric pressure equal to 14. Converting between bar pressure and PSI pressure is easily performed using this online conversion tool. TyreSafe makes every effort to provide accurate pressure information.

However, the accuracy of data cannot be guaranteed and users should consult their handbook for full approved settings. Please ensure your caravan’s MTPLM, number of wheels and tyre size have been inputted correctly before inflating your tyres to the suggested pressures. If in any doubt, please ask your vehicle manufacturer.

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. Severely underinflated tyre is a tyre under inflated by kPa ( Bar or psi) or more below the recommended pressure.

Calculating the tyre pressure most suited to a specific use of your tractor, or finding the recommended pressure for your site loader, we offer simple, intuitive tools that make life easier! Some newer caravans also include the tyre pressures, however many still do not have the tyre pressures include this is where this calculator can help. Also we need to know how many axels you have on the caravan. Typically you will have one axle (tyres), but possibly axles (tyres).

Keep your tyres inflated to the correct pressure by using this tyre pressure calculator and by following the instructions below. Check the sidewall of the tyres for the cold Inflation Pressure at Maximum Load (either kPa or psi) and the Maximum Tyre Load Rating (kg).

Always use the “SINGLE” load and pressure ratings. 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. Road Bike Tyre Pressures. These run at a high pressure to reduce the chances of punctures and reduce rolling resistance. Notably, narrow road bike tyres require the highest pressure.

Here is a guide that will help you equip your Erde trailer with tyre pressures recommended by the manufacturer. On a regular trailer tire you would inflate it to the max psi indicated on the tire because trailer tires are built with a thicker sidewall to handle more vertical load.

If a trailer tire is under inflate because of the thicker sidewall it will generate excessive heat and that is what leads to failure.
