The Semperit Speed-Life 3 tyre and the Kleber Dynaxer HP4 tyre, both manufactured for summer use, have been put through extensive tests and reviews to determine their performance and efficiency. Comparing these two models gives us insight into their strengths and weaknesses.

Though the Semperit Speed-Life 3 is a newer model replacing the Speed-Life model, it achieved a rating of 65% in our tests. Semperit's best features as proven by the ADAC test, include mileage efficiency and strong performance in wet braking. However, it has been observed to have drawbacks when it comes to dry road conditions, and there are some reservations on its environmental performance. Still, its efficiency and longevity in wet conditions cannot be overlooked.

Contrarily, the Kleber Dynaxer HP4 received a higher rating of 82% in our evaluations, with the key strengths being comfort and low levels of exterior noise according to the Autobild test. Additionally, the HP4 demonstrates good performance on dry roads and low fuel consumption as indicated in ADAC's 2021 test. On the flip side, the tyre appears to have an increased level of wear and tear and shows some weaknesses on wet road. Regardless, its overall performance and comfort stand out.

Comparing the two tyres, the Kleber Dynaxer HP4 performed relatively better than the Semperit Speed-Life 3 according to our rating system. When it comes to their test positions, both tyres fell within close range with the Semperit tyre taking the 12th position and the Kleber tyre close behind in 14th position in a total of 53 tyres tested by Autobild.
