7.5.5. Tyre pressure
The tyre pressure needs to be adjusted according to the terrain. In off-road (bumpy ground, uneven surfaces, fields, path, mud,
sand, snow ...) it is recommended to adjust to a low pressure (between 0.4 and 0.5 bar), this will mean a greater comfort of use.
Less inflated tyres provide better traction in mud, sand and snow.
To drive on firmer and smoother surfaces (asphalt), tyres can be inflated to a maximum pressure of 1.6 bar depending on the
user’s weight, preferences and driving ability. The table below can help you adjust the pressure of your tyres on the asphalt. It is
recommended not to inflate the tyres above 1.65 bar.
Tyre inflation should be checked weekly. All tyres are equipped with automotive type valves and can be inflated with most hand
or foot pumps, or with a compressor.
Warning: under-inflated tyres can be dangerous and are more at risk of puncture. Poor inflation pressure can affect chair
performance and pose risks.
Warning: over-inflated tyres can burst and cause injury. The recommended pressure is also shown on the flank of the tyre.
