How we calculate
Width, casing and compound decide how a tire really rides. We only show what was actually measured – and label estimates honestly.
Kenda Double Black: Reference: test pressure 24.7 psi (1.70 bar).
Specialized Butcher: 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.

Rubber compounds
Hardness scale 1 = hard and fast to 5 = very soft and grippy (our own classification).
Different grip classes: the softer tire must roll slower. Read the watts with that in mind.
Specialized Butcher offers the softer compound range – more grip, usually at the cost of wear.
Lab data per version
| Kenda Double Black | Specialized Butcher | |

| Puncture resistance (N) | – | 508.4 N |
| Weighed weight (g) | 1,036.0 g | 1,334.0 g |
These two tires have no measured values from the same test series. A direct comparison of numbers would not be sound.

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.
Three curves at most – hide one first.

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.

Tests and sources
Kenda Double Black
The Kenda Double Black was tested in its Pro AEC version as an enduro tire for both front and rear use. It impresses with good rolling characteristics combined with strong puncture protection. This positions it as a solid, versatile option in the enduro segment.
BIKE Magazin
Specialized Butcher
The editorial team tested the revised Specialized Butcher on trail and enduro terrain. The tire impresses with noticeably more cornering support and reliable grip on varying surfaces. Paired with the Eliminator, it forms a well-matched combo for aggressive riders.
MTB-News.deENDURO's lab test measures 64 MTB tires under standardised conditions (20 km/h, 1.5 bar, 50 kg wheel load) for rolling resistance, pinch-flat protection and puncture resistance. Key takeaway: weight and pinch-flat protection are closely linked, while rolling resistance depends mainly on the rubber compound. Summarised in our own words; details and measured values at the original.
