You can’t just take it for granted that tyres on your truck will take the weight of your demountable, especially so with Double Cab base cars. It’s crucial you check that they are rated correctly and have the correct pressure for the load you are carrying.
Our lightweight models should pose no problems but it’s always beneficial to take a trip to the local weighbridge. You don’t just want the overall weight, you need to ask the weighbridge to give you the front and rear axle weights too: this is very important. Before you go you should load the car and camper with all the stuff you take with you on your trips, a full tank of diesel and full fresh water tank. Don’t forget the driver and passenger must be included too.
If you are below the manufacturers GVW that’s a good start but it’s not the whole story. You need to check that both axles are within the truck’s axle limits too and that your tyres are rated to carry the load.
The maximum permissible axle weights will be shown on the vehicle data plate and you’ll find the rating of your tyres on the sidewall after the tyre size. The table below shows how the ratings work, for example 265 55 R16 108 T has a load capacity of 1000kg when inflated to the correct pressure. You’ll find that pressure prominently marked on the sidewall and remember it is always the pressure marked on the tyre, not the pressure on the information plate on the car that is correct. If they are different always trust the information on the tyre.
