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.

The Asymmetric 6 is the latest addition in the Eagle F1 range, offering great compromise between every day comfort and sporty driving. While it has dynamic steering response, it’s also very good on wet and has a low rolling resistance. Definitely recommended!

Ventus Prime 4 Is our favorite every day tyre, as it offers premium safety at an affordable price. Short braking distances, good handling, but slightly worse at aquaplaning and comfort.

The P Zero range is with us for a long time, also being a favorite choice for car manufacturers as first equipment. It’s a good, well balanced and enjoyable tyre. It tends to get quite a few mid-life updates so make sure you get the latest one.
