This test was conducted by TÜV SÜD Product Service GmbH between January and February 2025 (report number 713351940-PM), testing five premium all-season tires in size 205/55 R16 94V XL. The test was commissioned by Nokian Tires as part of their Premium Tire Mark certification for the Seasonproof 2, with the Nokian tire compared against the Bridgestone Turanza All Season 6, Goodyear Vector 4Seasons Gen-3, Michelin CrossClimate 2, and Pirelli Cinturato All Season SF 3. While TÜV SÜD is a fully independent testing organization with a strong reputation for objectivity, it is important to note that this test was requested and paid for by Nokian Tires.
Please also note, the TÜV SÜD report presents all results as percentages relative to the Nokian Tires Seasonproof 2, which is shown in the report as 100% in each category. The report does not include the actual measured values such as stopping distances, lap times, or other raw data. For this review, we have calculated estimated absolute values by applying the percentage differences to assumed baseline figures. These baseline values (such as 35 meters for wet braking or 18 meters for snow braking) are not from the TÜV report and should be treated as illustrative only. The percentage relationships between tires are accurate as reported by TÜV SÜD, but the absolute values are estimates created for easier comparison.
Now that we've got that out of the way, it looks like a strong result for the Finnish all-season contender! Don't spend too much time focusing on the overall result order at the bottom of the page, the test had quite limited data, but the SeasonProof 2 continues to be strong in the 16" size tested.
Dominant in Snow Braking and Snow Traction (1st, 100%) Consistently competitive across wet metrics (3rd–4th, 96.5–100%) Solid Rolling Resistance (3rd, 90%).
Dry Braking only mid-pack (4th, 96%) Wet Handling behind leaders (4th, 96.5%) Not class-leading in aquaplaning (3rd, 99.6%).
Nokian Seasonproof 2 wins on winter performance with best-in-test Snow Braking and Snow Traction, plus strong Snow Handling (2nd, 99.6%). It remains competitive in wet disciplines, landing 2nd–4th with percent_of_best between 96.5% and 100%, and offers respectable Rolling Resistance (3rd, 90%). Its main compromises are Dry Braking (4th, 96%) and Wet Handling (4th, 96.5%), but its balanced showing and standout snow capability secure a top overall result.
Wet Handling and Straight Aqua leader (1st, 100%) Strong Dry Braking and Wet Braking (2nd, 99.4% and 98.6%) Consistent wet-weather dominance.
Weak snow package (4th in Snow Braking and Snow Handling, 94.7% and 95.1%) Average Snow Traction (3rd, 97.6%) Highest Rolling Resistance (5th, 81.8%).
Pirelli Cinturato All Season SF3 excels in wet with class-leading Wet Handling and Straight Aqua, backed by strong Dry Braking and Wet Braking. Its snow results are notably weaker, ranking 3rd–4th across Snow Braking, Snow Traction, and Snow Handling, and it posts the poorest Rolling Resistance (5th, 81.8%). The profile suits wet and dry priorities over winter efficiency.
Best Rolling Resistance (1st, 100%) Snow Handling winner (1st, 100%) with strong Snow Braking/Traction (2nd, 99.4–99.8%) Solid Dry Braking (3rd, 98.2%).
Weak wet performance: Wet Braking (4th, 92.5%) and Wet Handling (5th, 93.4%) Straight Aqua only mid-pack (4th, 97.9%) Not a wet specialist.
Michelin CrossClimate 2 blends best-in-test efficiency with winter confidence, topping Rolling Resistance and Snow Handling while staying near the front in Snow Braking and Snow Traction. Dry Braking is solid, but wet metrics are its drawback, with lower Wet Braking and Wet Handling and a mid-table Straight Aqua result, placing it behind the wet leaders overall.
Best Dry Braking and Wet Braking (1st, 100%) Top-tier wet dynamics (Wet Handling 2nd, 98.9%; Straight Aqua 2nd, 100%) Strong all-rounder in dry/wet.
Weak snow performance across all snow tests (5th, 90.6–92.8%) Rolling Resistance below average (4th, 85.1%) Winter capability lags rivals.
Bridgestone Turanza All Season 6 dominates dry and wet stopping and is excellent in wet dynamics, but its snow performance is the lowest across Snow Braking, Snow Traction, and Snow Handling. With below-average Rolling Resistance, it’s optimized for dry and wet rather than winter conditions.
Good Rolling Resistance (2nd, 92.6%) Balanced snow showing (3rd in Snow Braking and Snow Handling, 98.6–99.4%) Decent Wet Handling (3rd, 97.6%).
Weak Dry Braking (5th, 88.7%) Weak Wet Braking (5th, 87.5%) and Straight Aqua (5th, 96%) Snow Traction only 4th (97.6%).
Goodyear Vector 4Seasons Gen 3 offers efficiency and acceptable winter balance, with strong Rolling Resistance and solid Snow Braking/Handling. However, it struggles in key safety stops, ranking last in Dry and Wet Braking and in Straight Aqua, limiting its overall standing despite decent Wet Handling.
