Tire Pressure for Hymer from 1985 to 1990

When you buy an old motorhome and it has been sitting for a while without moving, you want to check your tire pressure and their respective condition. You don’t want rotting tires or any signs of fatigue as it could dramatically impact your safety on the road. As for most old Hymer models (before 1995), it is difficult to find the correct tire pressure for each model.

There isn’t one exact tire pressure number for each tire, but you should have a pressure that follows how much your motorhome is loaded. Each Hymermobil will be loaded with different additions, material, and personal stuff following their owner.

Therefore, the only correct way to know your exact tire pressure is to individually weigh your front and rear axels, contact your tire manufacturer with and he should be able to give you the exact pressure needed for each one.

As general guidance, Hymer indicated on their manual the recommended pressure in bar for each axle. You can follow these numbers and adjust them accordingly to your load.

I own a Hymermobil 560 since 2017 and I’ve been putting 3,25 bar and 4,50 bar for the front and rear axle respectively and everything is going smoothly. When I go off-road (when possible), I deflate a little bit each tire by 0.5 bar to get better traction.

Lastly, remember that you should always check your tire pressure and general state for safety reasons before driving.
