Comparison: Petlas Imperium PT515 vs. Semperit Speed-Life 3 vs. Barum Bravuris 5 HM vs. Goodyear Efficient Grip Performance vs. Cooper Zeon CS8 vs. Uniroyal RAINEXPERT 5 vs. Michelin Primacy 5 vs. Firestone Roadhawk 2

When comparing the Petlas Imperium PT515 and the Semperit Speed-Life 3 tyres, several differences come to light. Both models are summer tyres, though their performance, as demonstrated through various tests, varies.

The Petlas Imperium PT515 holds our rating of 48%. Manufactured in Turkey, the Petlas model doesn't excel in terms of performance. In Autobild's comparison, it acquired 35th place out of 53, showcasing major areas of improvement. In the ADAC's test, the model was slightly more favourable, occupying the 14th place out of 15 tested tyres. According to Autobild 2022, the Petlas Imperium PT515 shows high mileage and little wear, but significant weaknesses on both wet and dry surfaces, and sustainability are problematic. Its weight is also comparatively heavy, leading to a rather unbalanced performance overall.

In sharp contrast, the Semperit Speed-Life 3, a product from the Semperit brand, scores a substantially better rating of 59%. In the Autobild's test, it accomplishes a remarkable 12th rank, pushing ahead of numerous peers. It outshines the Petlas model even more in the ADAC's test, coming 2nd out of 15 tyres, praised specifically for its exterior noise and wet braking performance. As per Autobild 2022, the Semperit Speed-Life 3 shows a strong performance on wet roads, efficiency, and considerable mileage, while displaying minor weaknesses on dry roads and in terms of environmental balance.

The direct comparison of these two models points towards the Semperit Speed-Life 3 as the more reliable and efficient choice among the two, especially when considering the all-rounded performance indices. The obvious advantage of this model is not only its strength in wet braking but also its noise control. Conversely, the Petlas Imperium PT515 may need improvements to compete effectively with counterparts, considering its shortcomings in various areas, from balance to sustainability.

While both models have no newer versions or models that have replaced them, Semperit Speed-Life boasts a history, improving from the previous model, Semperit Speed-Life.

In conclusion, based on test results, the Semperit Speed-Life 3 is the more recommendable option, yet the final decision should be made considering individual requirements, driving conditions, and budget constraints.
