Comparison: Vredestein ULTRAC vs. Michelin Primacy 4+ vs. Continental PremiumContact 6

When comparing the Vredestein ULTRAC and the Michelin Primacy 4+, we can see some noticeable differences, particularly in performance, strengths, and weaknesses, offered by these two summer tyres manufactured by Vredestein and Michelin respectively.

With a rating of 21%, the Vredestein ULTRAC stands out for its features such as Aquaplaning - longitudinal, Aquaplaning - cross, and Dry handling, earning it the 2nd position in the ACE test out of 10 tyres. It also received commendable feedback in the Autobild and Automotorsport tests, earning 3^rd position in both. However, it has been marked down for its high rolling resistance, high external noise, increased understeer on wet and dry tracks, and slightly prolonged braking distances.

Made in Spain, the Michelin Primacy 4+, with a rating of 76%, surpasses its competitor from Vredestein in many aspects. It has been replaced by a newer model, the Michelin Primacy 5. Notably, it showcased its strength in Dry handling in the ACE test, even if it only reached the 3^rd place. In the automotorsport test, it got the 8th position but did surprisingly better in the ADAC and Autoklub ČR tests where it secured the 2^nd spot. It struggled with long braking distances, weak cornering grip and poor traction on wet road conditions, and an increased risk of oversteering during quick lane changes and in load-altering situations.

In conclusion, the Michelin Primacy 4+ appears to have a better overall performance, primarily due to balanced capabilities, secure properties on both dry and wet tracks, and an impressively high projected mileage coupled with low weight and fuel consumption. On the other hand, the Vredestein ULTRAC seems to falter on a couple of points, such as increased rolling resistance and exterior noise, and it shows lower mileage projection and high wear and tear, which might be relevant if you are considering the value for money. However, it holds up with its secure handling properties and universally good aquaplaning characteristics.

It's important to consider your driving preferences, conditions, and needs before making the final decision between these two options.
