Tyre pressure control system
Halving the tyre pressure off-road means doubling the ground contact
area and the tractive force.
Traction conditions depending on the tyre pressure
High tyre pressure on the road
• Small contact area
• Low tyre wear
• Low fuel consumption
• High load capacity at
high speed
• Good track-holding and
very stable steering
Low tyre pressure off-road
• Large contact area
• Low ground pressure,
less field damage
• Less slip
• High traction
• Good self-cleaning (tread)
• Minimal ground compaction,
fewer ruts
• No getting stuck
