Continental did it again with the PremiumContact 7. It’s an incredibly well balanced tire with just the right wet and dry grip and above average mileage. Since it’s launch in 2023 it got nothing but the best results in the tests, the only downside being it’s premium price.
The Turanza T005 was introduced in 2018, but still stands as a great tyre, offered in incredible 350 different sizes. It’s universal also in it’s properties - it’s a balanced mix of wet and dry performance with above-average rolling resistance.
The Turanza 6 is quite a new addition to Bridgestone’s lineup, being introduced in 2023. Featuring the new ENLITEN technology, it should be lighter and have positive effect on fuel efficiency. In the tests, the efficiency is confirmed alongside with higher mileage. That being said, it somehow lacks the performance of other premium tyres, so we would recommend it only when the price is lower.
Firestone, the affordable brand belonging to the Bridgestone group, has a fresh addition to their lineup - the Roadhawk 2. And it seems like it’s set off for success - it offers the Bridgestone’s ENLITEN technology, which makes the rolling resistance and mileage exceptional for a budget tyre and it combines it with safe behavior on wet and dry.
