How we calculate
Width, casing and compound decide how a tire really rides. We only show what was actually measured – and label estimates honestly.
Continental Cross King: Reference: recommended pressure 24 psi (1.65 bar) – an assumption, not a test pressure.
Schwalbe Racing Ray: Reference: recommended pressure 24 psi (1.65 bar) – an assumption, not a test pressure.
More pressure: less rolling resistance, less grip, less comfort. Tougher casing: more protection, more weight. Softer compound: more grip, more rolling resistance.
Modelled values are assumptions based on the stated measurement points – not a lab test.

Rubber compounds
Hardness scale 1 = hard and fast to 5 = very soft and grippy (our own classification).
Both tires sit in the same grip class – the watt comparison is fair.
Both tires sit on the same step of our editorial hardness scale.

The curve shape is a physics model, not a measurement. Labs do not measure grip across pressure – we do not invent that curve. Wet grip is a lab value per tire model, not per version.
Three curves at most – hide one first.
Variants head to head
Every measured variant of the selected tires – the same model in another compound, width or casing sits right next to it. Empty fields mean no reliable measurement.
