How often should the tyres on your caravan be changed?

Wednesday, November 12th, 2008



Preferably replace any tyre more than five years old, but never exceed seven.
They will have significantly deteriorated by then, whatever the tread depth or amount of use. Remember that generally a caravan will travel far fewer miles than an average car and therefore the car tyres are normally wear to their limits within a five year period.

Some essential caravan terminology

Wednesday, November 12th, 2008



MiRO (Mass in Running Order)


– This is the caravan’s weight with all factory fitted equipment, when it leaves the factory. MiRO replaces the old terms ‘ex works weight’ and ‘unladen weight’.


MTPLM (Maximum Technically Permissible Laden Mass)


– The maximum weight that the caravan chassis can take, as stated by the manufacturer of the chassis. It replaces Gross Vehicle Weight.



Payload


– The weight of items you could load into your caravan. It is derived by subtracting the caravan’s MiRO from its MTPLM.


Nosewight


– This is the weight applied to the towball by a caravan. It is important that the maximum noseweight is not exceeded. Both the car and tha caravan have maximum noseweight limits. The lower of the two is the legal maximum.


GTW (Gross Train Weight)


– The maximum combined weight of a car and trailer combination.



Towing limit


– The maximum weight of a trailer that a car may legally tow. It is often higher than the kerbweight.


Kerbweight


– As defined by EU Directive 95/48/EC. The vehicle’s weight with its fuel tank 90% full, all necessary fluids, driver and luggage of 75KG.
