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: 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.

Lab data

Real test-rig values – not an estimate. Tested variant: Aspen ST MaxxSpeed EXO/TR Team Spec 2.4 (gemessene Variante).

Watts measured on the test rig: lower is better. The 1-10 ratings on this page: higher is better.

No lab of our own: measurements come from the third-party test named above – the source is linked directly.

Automatic assessment

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

  • Rolling resistance

    Weaker in comparison

    26.7 W · rank 14 of 20 comparable XC tires

    10 W behind the best value in the same test series. Fewer watts is better – every watt saved stays in the drivetrain.

  • Wet grip measurement

    65 points · rank 11 of 20 comparable XC tires

    7 points behind the best value in the same test series. More points means more compound grip on smooth surfaces.

  • Weighed weight

    Mid-field

    699 g · rank 9 of 20 comparable XC tires

    107 g behind the best value in the same test series. Fewer grams is better, but usually costs casing stability.
