Our favorite every-day performance tyre that delivers fast laps on dry circuits while being safe for the daily commute, having won multiple tests in wet conditions. However, if you lean more towards comfort and low rolling resistance, the PremiumContact 7 might be a better choice.

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.

Pilot Sport 4S is the sportier version of the Pilot Sports and the most sporty one that still cares about the wet performance, which is it's strong suite. It's usually expensive, but also a guarantee of a great performance tyre.

One of the cheaper tyres that can be recommended as it hasn't failed a single test and is often rated as a economical choice. It's surprisingly quiet, so if you are looking for a good and comfortable tyre, Azenis FK520 could be a tyre for you.

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.
