Lewis Hamilton’s F1 Japan GP woes caused by tyre wear, not Ferrari SF-26 power unit. Suzuka analysis: Tyre wear behind Lewis Hamilton’s Ferrari struggles.

Insights have emerged regarding Lewis Hamilton’s performance issues during the Japanese Grand Prix, clarifying that engine problems were not to blame. After two races where the Briton kept close to, and occasionally outperformed, teammate Charles Leclerc, the seven-time world champion faced unexpected difficulties behind the wheel of his Ferrari SF-26 at Suzuka.

Why Lewis Hamilton lagged behind Charles Leclerc in Japan

Lewis Hamilton’s qualifying pace in Japan was competitive, with the British driver posting times just a tenth slower than Charles Leclerc. However, during the race, the former Mercedes man struggled to maintain consistent lap times and fell behind his Ferrari teammate. While some observers speculated that Hamilton’s post-race comments about needing an engine change before the Miami Grand Prix hinted at power unit or battery issues, further analysis has painted a different picture.

Tyre degradation emerges as the main challenge

According to reports from the Italian website AutoRacer, the primary factor limiting Lewis Hamilton’s pace was tyre degradation. The SF-26’s hard tyres suffered greater wear on Hamilton’s car than on Charles Leclerc’s, leading to more tyre slip and higher energy consumption throughout each lap. This discrepancy forced Hamilton’s engineers, led by Carlo Santi, to instruct the British driver to ease off the throttle by approximately 15% at strategic points. The temporary reduction in throttle helped conserve energy for crucial moments of the race, but it prevented Lewis Hamilton from consistently matching his teammate’s speed.

Ferrari’s strategy to overcome performance gaps

The Japanese Grand Prix has highlighted areas for Ferrari to address as the team prepares for the next phase of the 2026 season. Engineers are now analyzing the Briton’s telemetry and tyre data in depth to develop strategies that will reduce tyre wear and optimize energy deployment. The Scuderia aims to bring improvements before the Miami Grand Prix, allowing both Lewis Hamilton and Charles Leclerc to extract the maximum performance from the SF-26 and keep Mercedes and other rivals under pressure.

Looking ahead: Hamilton and Ferrari’s path to competitiveness

While the Suzuka struggles were a setback for Lewis Hamilton, they were not due to any fundamental flaw in the Ferrari SF-26 power unit. Instead, tyre management and energy conservation played a critical role. As Ferrari continues to refine its strategy, engineers hope that the Briton will be able to maintain pace with Charles Leclerc consistently, giving the team a stronger chance to compete at the front of the grid in upcoming races. The lessons learned in Japan are expected to influence both car setup and race strategy for the remainder of the 2026 Formula 1 season.

The Maranello team’s focus on tyre performance and race energy management may be the key to unlocking Lewis Hamilton’s full potential in the SF-26, ensuring he can challenge for podiums alongside Charles Leclerc and keep pressure on Mercedes as the championship unfolds.
