The 2025 Sport Auto UUHP tire test is the first to test the new Falken Azenis RS820!
The test used a G series BMW M4 with 275/35 R19 front and 285/30 R20 rear tire sizes. Sport Auto evaluated four performance tires: Continental SportContact 7, Michelin Pilot Sport 4S, Falken Azenis RS 820, and the BMW OE-marked Pirelli P Zero (PZ4*). Testing covered wet and dry braking, handling, aquaplaning resistance, and rolling resistance.
Continental won the test with a score of 9.6, thanks to superior wet performance and the lowest rolling resistance. Michelin placed second at 8.5 points, while Falken (7.0) and Pirelli (6.8) followed behind.
OE vs Aftermarket Performance
The test revealed significant differences between the OE-marked Pirelli P Zero and the aftermarket alternatives. The Pirelli tire, which is factory-equipped on new BMW M models, showed notable shortcomings in wet braking. Its stopping distance from 50 mph on wet surfaces was nearly 26 feet longer than the Continental.
Sport Auto suggests the OE tire's firmer rubber compound, likely designed for higher mileage and lower rolling resistance to meet manufacturer specifications, compromises wet weather performance. As vehicles age, the magazine recommends considering aftermarket options like the Continental SportContact 7, which offers improved safety margins particularly in wet conditions.
While the Pirelli demonstrated predictable handling characteristics with a tendency toward understeer, it required larger steering inputs and provided less feedback than the Continental and Michelin alternatives. This translated to a less engaging driving experience that masked some of the M4's dynamic capabilities.
Dry
In dry braking the Continental SportContact 7 delivered the shortest stopping distance from 100-0 mph, with all four tires showing relatively minor performance differences of just 4 feet between best and worst.
