Bridgestone Turanza 6
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.
- Low rolling resistance/low fuel consumption
- Longer braking distance on dry roads
- High drive-by noise levels
- Poor handling on the wet
