Comparison: Semperit Speed-Life 3 vs. Nokian WetProof vs. Goodyear Efficient Grip Performance 2 vs. Michelin Primacy 5

The Semperit Speed-Life 3 and the Nokian WetProof are both summer tyres, however, they have differing performances according to various tyre tests conducted. The Semperit tyre, manufactured by Semperit, secures a rating of 47% in our tests, while the WetProof tyre, produced by Nokian, attains a higher score of 68%.

Semperit Speed-Life 3 ranks as the 10th best tyre out of a field of 19 in the Autoklub ČR tests, with its best features being exterior noise and wet braking. But it slips to the 12th position in the Autobild test, with its best features again depicting its performance in wet conditions. ADAC, however, rates the Semperit tyre quite higher, where it attains the 2nd position among 15 tyres tested, primarily owing to its exterior noise and wet braking abilities.

In the same Autoklub ČR evaluation, the Nokian WetProof ranks as the 6th best tyre, with its standout feature being exterior noise. It also attains good scores in the Autobild test, coming in at 6th position among 53. However, ADAC, places it at 11th position, albeit highlighting its superior noise and wet circle cornering abilities. Which is particularly understandable with the tyre's inherent "WetProof" feature.

From the Autoklubcr 2023 text summary, both tyres have their strengths and weaknesses. The Speed-Life 3 is efficient and performs well on wet roads, but reveals some weaknesses in dry conditions and stands accused of an unfavorable environmental balance. Meanwhile, the Nokian WetProof presents balanced performance on both wet and dry roads and is also efficient. However, it shows some weaknesses concerning tread wear and sustainability, and is rated poorly regarding environmental balance.

On the whole, based on the summarized data provided, Nokian WetProof seems to have an edge over the Semperit Speed-Life 3 in tire test comparisons, despite a lower rating in the ADAC test. Neither of these tyres have been replaced by newer models according to the currently available information.

Verdict: If balanced performance and efficiency are your prime interests, while acknowledging potential tread wear and sustainability issues, you might be better off with the Nokian WetProof. Whereas those who weigh wet performance and low noise higher than dry road performance might consider the Semperit Speed-Life 3.
