Road Tires vs Track Tires vs Slick Tires
Compare each discipline in the tested size. See the measured result, position and gap to the best tire, then read the verdict for the trade-offs behind the finishing order.

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 tires can be separated by very different margins.
Positions and gaps always refer to the full test field within each group. Selecting tires 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.

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.
Dry Handling
For dry handling, I drive at the limit of adhesion around a dedicated handling circuit with ESC disabled where possible so I can assess the tire's natural balance, transient response, and limit behavior without electronic intervention masking the result. I usually complete between two and five timed laps per tire set, depending on the circuit, tire type, and consistency of conditions. I exclude laps affected by clear driver error or obvious environmental inconsistency. Control runs are carried out frequently throughout the session, and I often use multiple sets of control tires so that wear on the references does not become a meaningful variable. For more track-focused products, I also do endurance testing, which is a set number of laps at race pace to determine tire wear patterns and heat resistance over longer driving.
