How we calculate

Width, casing and compound decide how a tire really rides. We only show what was actually measured – and label estimates honestly.

Reference: test pressure 24.7 psi (1.70 bar).

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.

Without a lab test pressure we anchor the measured watt value at the recommended pressure. 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.

Automatic assessment

Tested: Calculated from the stored measurements – compared only within the same test series and category (Enduro).

Rolling resistance

36.7 W · rank 13 of 31 comparable Enduro tires

41.4 % · rank 18 of 33 comparable Enduro tires
44.1 % behind the best value in the same test series. A higher percentage is better – the tire cushions hard edges for longer.

The familiar pattern: the easy roll is paid for with less impact protection.

The new Schwalbe Albert with its revolutionary radial casing is examined for grip in this test. The massive, rounded knobs are meant to give the tire predictable, forgiving handling.
