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 · 100% | ||
| Dry Handling | 83% | 83% |
| Subj. Dry Handling | 17% | 17% |
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 tyre's natural balance, transient response, and limit behaviour without electronic intervention masking the result. I usually complete between two and five timed laps per tyre set, depending on the circuit, tyre 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 tyres 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.
Subj. Dry Handling
I also carry out a structured subjective handling assessment at the limit of adhesion on a dedicated dry handling circuit. I score steering precision, steering response, turn-in behaviour, mid-corner balance, corner-exit traction, 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.
The reason for this test was to see if a lower treadwear value, which is a number the American Uniform Tyre Quality Grade (UTQG) standards body assign to a tyre based on a basic wear test, really does mean more grip, but it turned out to be a fascinating insight into some of the big hitting tyres used on track in North America.
The surprise of the show was the Goodyear Eagle F1 SuperCar 3. Sadly this tyre isn't available in Europe, and sits somewhere between the Michelin Pilot Sport 4 S and Cup 2. Dynamically it's outstanding for its sector, with crisp steering and great feedback, and good grip to match, finishing just a little slower than the Cup 2.

The Michelin Pilot Sport 4S, which is a UUHP road tyre, almost matched the one lap pace of the Toyo R888R, which is either very good for the Michelin or very bad for the Toyo. The internet seems to love the R888R, so perhaps it works better in smaller sizes on lighter cars, but on this 305/30 R19 it was a difficult tyre at the limit. If you drove at 9/10th, it felt great, but when you tried to extract the final pace from the tyre is gave very poor feedback and seemingly random grip.
As for the original question, does a lower treadwear rating mean more grip, if we ignore the Toyo yes it does, but thanks to the Toyo, in this test, it does not.
