Ranked #4 of 9Securing the fourth spot among nine competitors, the Vredestein Ultrac proved itself as a competent all-rounder in its performance evaluation. Though it didn't reach the top marks in any specific category, it was commended for its solid grip level, comfortable driving experience, and high energy efficiency. However, its longer braking distance on wet surfaces was noted as a drawback. On dry surfaces, the tire's low rolling resistance coefficient highlights its fuel-saving potential, but it was the slowest in the slalom segment. Despite this, it was praised for its good cornering grip and straightforward handling, with a gentle understeer that signals well in advance, enabling easy control adjustments by the driver. The clear feedback on wet surfaces demands precise input from the driver, rewarding with considerable grip levels, although the long braking distance on wet conditions was a pointed concern.
Autobild Summer tyre test 2024 225/55 R17 satisfactory Ranked #7 of 10Finishing 7th out of 10 competitors, the Vredestein ULTRAC tyre received a final rating of 'Satisfactory'. It was praised for its brand-quality sidewall stability and secure driving characteristics, alongside good aquaplaning resistance and pleasantly quiet rolling comfort, all available at a moderate price level. However, its performance was slightly marred by a tendency to understeer on both wet and dry surfaces, increased rolling resistance, and marginally extended braking distances. No specific disciplines were highlighted as its strongest or weakest points, underlining its overall satisfactory but mixed performance.
