For your safety and also to make sure that your trailer is reliable, it is important that you regularly carry out thorough checks to establish the general condition of your trailer and its tyres. A good set of tyres and a stable load increase road safety significantly.
The tyres on your trailer are the only parts of the trailer that are in direct contact with the road surface. This explains why the condition of your tyres largely determines a trailer's grip on the road and its road handling. Tyre pressure and tyre tread in particular majorly affect the safety of your means of transport. With this in mind, we advise that you check the tyres on your trailer for the following every two weeks:
If in any doubt, always contact your Hapert Dealer.DO YOU NEED NEW TYRES?
The correct tyre pressure promotes road handling and improves road safety. If tyre pressure is optimal, the trailer will brake better, there will be a minimal risk of swerving, tyre wear will improve and the chance of a burst tyre will become significantly lower. You will use less fuel too. All in all, it is vital to check your tyre pressure on a regular basis.
The optimum tyre pressure for your HAPERT trailer
will depend on the type of tyre you are using.
The tyre pressure table below shows the
appropriate tyre pressure and also
the maximum load per type of tyre.
* The Bar pressure-unit is used to indicate tyre pressure.
** Pound per Square Inch is a unit of pressure that is used primarily in the United Kingdom and the United States.
The information provided on the side of a tyre tells you about the construction and properties of the tyre in question:
Trailer tyres lose their tread depth through wear over time. It is against the law to drive with tyres that have an overall tread depth of less than 1.6 mm. We describe two easy ways for you to check tyre tread yourself below.
You will see the abbreviation TWI (Tread Wear Indicator), a triangle or the brand logo on a number of places on the side of the tyres on your trailer. This wear indicator, which consists of a small block that is 1.6 mm thick, enables you to see how worn your tyres are straight away. The wear limit will have been reached once you can see the block indicated above.
A slide gauge or tyre-tread gauge makes it easy to measure the tread on a tyre. Always make sure that you measure the tread in three places: the middle, inside and outside of the tyre. This is important because the tyres on your trailer may wear more in one area than they do in others. With this in mind, the tread depth of a tyre is always determined on the basis of the lowest tread measured.
