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.

The Pilot Sport range from Michelin is now almost legendary, with the Cup variants being the fastest road legal tyres available. But the ‚ordinary‘ Pilot Sport 5 not as spory as it’s name suggest - it’s incredibly well balanced, with the priority being low rolling resistance and high mileage over sporty handling. It’s still a Michelin tire, so higher price is to be expected.

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!

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.

Did you know ...?
255/40 R21 doesn't belong to the most popular dimensions for summer tyres - there are 9 tyre models available, which can be compared to 165/80 R13, 155/70 R19, 155/80 R13. Let's break down the sizing - 40 is height of the tyre, which is calculated as 40% of the tyre width (255mm), which means the sidewall height has 102 mm. The wheel diameter is R21, which means it fits to a 21 inch/533.4mm diameter wheel. The total circumference of the tyre is 2316.61 mm, which is very similar to 255/45 R20(2316.92 mm), 235/65 R17(2316.3 mm), 255/50 R19(2317.24 mm), 255/55 R18(2317.55 mm), 255/60 R17(2317.87 mm), 255/65 R16(2318.18 mm), 255/70 R15(2318.5 mm). There are multiple speed indexes available for summer tyres in 255/40 R21: H(210km/h), T(190km/h), V(240km/h), W(270km/h), Y(300km/h). The same goes for weight indexes: 102, 105.
