Presentation on single-wheel trailer technology for measuring tyre wear on C1, C2, and C3 tyres. The document describes a narrow trailer with one measuring wheel that eliminates vehicle-specific influences such as axle geometry, suspension kinematics, and drivetrain concepts to enable direct comparison of tyres from different manufacturers. The trailer uses a Cardan joint coupling that transmits roll movement from the towing vehicle while allowing pitch and yaw movements, with adjustable ballast positioning to control wheel load. Comparison tables show that the single-wheel trailer method produces results similar to outdoor convoy testing for lateral force, braking force, and camber while avoiding wheel load transfer effects present in conventional vehicle testing.
