On the other hand, the Uniroyal RainSport 5 performs well in wet conditions, showing good aquaplaning qualities and secure wet handling, as noted in the Autobild 2024 test.

It also scores low on environmental balance and sustainability, with lower mileage and higher fuel consumption, as evidenced in the Autoklub ČR 2023 test.
