Continental SportContact 7
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.

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.

Goodyear Eagle F1 Asymmetric 6
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!

Firestone Roadhawk 2
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.

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.

Pirelli P Zero PZ4
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.
