AutoMotorSport Summer tyre test 2022 245/45 R19 sufficient Ranked #10 of 10Finishing 10th out of 10 competitors, the GT Radial Sport Active 2 was given a final rating of 'Sufficient.' It was recognized for offering good aquaplaning prevention and maintaining secure, easily controllable cornering behavior on dry roads, alongside reliable performance during sudden evasive maneuvers. However, it faced criticism for having the longest braking distances on both wet and dry asphalt, lower driving stability in wet corners, and was deemed more suitable for lighter, less powerful vehicles. This was primarily due to significant safety compromises despite being a budget-friendly option. Notably, the tire excelled in aquaplaning resistance in cross conditions and producing low exterior noise, showcasing some strengths amidst its limitations.
