2025 AMS Sustainability Tire Test
The Insa Turbo EcoEvolution is a retreaded tire that performed poorly across nearly all test categories. While the concept of reusing tire carcasses is fundamentally sustainable, the execution failed to meet basic safety standards. The tire exhibited extremely poor grip on both wet and dry roads with dangerously long braking distances. It showed unsafe, heavily understeering, and unpredictable handling dynamics. The tire had poor construction quality with uneven surfaces causing vibrations and loud interior noise. Despite its low price, its extremely high rolling resistance caused over 10% increased fuel consumption. It failed the high-speed test and received a "deficient" overall rating with the recommendation not to use it on passenger cars.
