Read the measurements, not just the rank

Lower is better for braking distances and lap times; higher is better for subjective scores and aquaplaning speed. Bars start at zero. Read the gap alongside the position: adjacent tyres can be separated by very different margins.

Positions and gaps always refer to the full test field within each group. Selecting tyres does not recalculate rankings or change the best-in-test benchmark.

Score Weighting

Weights express the scoring priorities, not how much each discipline actually changed the finishing order. The size of the performance gaps matters too. Category weights contribute to the overall score. Within each category, discipline weights divide that category’s share. Published finishing positions also need to be read alongside the editorial verdict.

Test	Within category	Share of overall score
Dry · 35%
Subj. Road Score	100%	35%
Off road · 35%
Subj. Dirt Handling	100%	35%
Comfort · 30%
Subj. Comfort	50%	15%
Subj. Noise	50%	15%

Our standard methods

The conditions above are recorded for this test. The descriptions below explain our standard procedures; measurement windows and run counts can vary by test.

Subj. Road Score

I use a broader road score to capture how a tyre performs in normal real-world use across motorways, rural roads, and urban environments over an extended drive of typically 100 km or more. This assessment includes ride comfort, cruising noise, wet-weather confidence, steering feel, lane-change stability, straight-line stability, and overall predictability. It is intended to reflect the cumulative real-world impression a tyre creates outside the constraints of short-format instrumented testing. Rated on a 1–10 scale.

Subj. Dirt Handling

I also carry out a structured subjective handling assessment on a dedicated dirt course. I score steering feel, traction, stability, breakaway characteristics, and overall confidence using a standardised 1–10 scale used consistently across my testing. The final assessment combines numeric scoring with written technical commentary. I complete familiarisation laps on the control tyre before evaluating each candidate.

Subj. Comfort

To assess comfort, I drive on a wide range of road surfaces (often dedicated comfort tracks at test facilities) at speeds from 50 to 120 km/h, including smooth motorway, coarse surfaces, expansion joints, broken pavement, and sharp-edged obstacles. I evaluate primary ride quality, secondary ride quality, impact harshness, seat-transmitted vibration, and the tyre's ability to absorb sharp inputs. Ratings are assigned on a 1–10 scale relative to the reference tyre.

Subj. Noise

For subjective noise assessment, I drive at constant speeds across multiple surface types with the windows closed, ventilation off, and audio system off. I assess overall noise level, tonal quality, cavity boom, pattern noise, broadband roar, and sensitivity to both speed and road texture. Each tyre is rated on a 1–10 scale and supported by written observations on noise character and annoyance.
