51 % · rank 11 of 33 comparable Enduro tires
34.5 % behind the best value in the same test series. A higher percentage is better – the tire cushions hard edges for longer.
Sehr offenes Stollenprofil, ausgelegt auf weichen und matschigen Untergrund.
Width, casing, compound and pressure – every value on this page follows your pick.
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.
Editorial assessment on a 1–10 scale. Grip index: 8.9
These grades describe the tire model, not one specific width or compound – no reliable per-version grades exist.
Scores from 1 to 10: higher is better.

The value in brackets is our brand-neutral casing class (Light, Trail, Enduro, Downhill) – not a manufacturer statement.
Real test-rig values – not an estimate. Tested variant: Verdict SG1 TriTec High Grip Tough 29 x 2.50.
Watts measured on the test rig: lower is better. The 1-10 ratings on this page: higher is better.

Strong in comparison
51 % · rank 11 of 33 comparable Enduro tires
34.5 % behind the best value in the same test series. A higher percentage is better – the tire cushions hard edges for longer.
Weaker in comparison
424.1 N · rank 11 of 14 comparable Enduro tires
173.2 N behind the best value in the same test series. More newtons is better – the casing withstands sharp rocks for longer.
Weaker in comparison
1,311 g · rank 21 of 31 comparable Enduro tires
329 g behind the best value in the same test series. Fewer grams is better, but usually costs casing stability.

ENDURO Mountainbike Magazine – Labortest
January 2023ENDURO'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.

October 2025WTB's revised gravity tires Verdict and Judge were examined together in this test. The new SG1 puncture protection and dual-layer TCS Tough casing provide high stability during high-speed descents. The high-grip compound also delivers dependable traction on demanding terrain.

June 2019The WTB Verdict was tested as a specialized gravity tire under demanding enduro and bike park conditions. The massive knobs provide strong grip on rough, loose terrain but require some familiarization. Overall, it shows a clear character suited to descent-focused riders.
