There is another important point to ensure safety and vehicle stability: the tyres of your motorhome must be inflated to the correct pressure. Indeed, the volume and pressure of the air inside the motorhome tyres determine the load they are able to carry.
Motorhome tyres with a CP marking are designed to run at a higher pressure than the pressure for vans (C marking), which gives better handling and increased resistance to the load characteristics of large Motorhomes.
For CP tyres fitted to Motorhomes, the ETRTO advises:
- On the rear axle: the motorhome tyre pressure should be 5.5 bar (80 psi). The maximum load capacity of the tyre must be respected. (Note that the use of a metal clamp in valve or specific high pressure rubber valve is required above 4.5 bar (65 psi)),
- On the front axle: refer to the manufacturer's inflation recommendations indicated on the vehicle and / or its handbook.
Don't forget that your motorhome tyre pressures should be checked and adjusted as necessary, monthly and before a long journey.
