Bridgestone Potenza Sport
We really like the new Potenza Sport, as it’s more sporty and dynamic than the usual tyre in this category, but still perfectly usable and safe for everyday driving, which makes it unique. It’s rolling resistance, mileage and overall comfort are also on a good level, except for a slighty higher noise.
- Exceptional handling on the wet
- Short braking distance on wet roads
- Great handling on dry roads
- Short braking distance on dry roads
- Excellent steering response on dry roads
- High rolling resistance/high fuel consumption
- High drive-by noise levels
