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 Bridgestone Potenza Sport Evo is the successor to the multi-award-winning Potenza Sport, featuring ENLITEN Technology for enhanced performance. It delivers 5% shorter wet braking, 2% shorter dry braking, and 15% greater mileage compared to its predecessor, while achieving EU label A-grade wet grip.

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.

265/45 R18 doesn't belong to the most popular dimensions for summer tyres - there are 6 tyre models available, which can be compared to 155/60 R15, 170/60 R17, 160/60 R14. Let's break down the sizing - 45 is height of the tyre, which is calculated as 45% of the tyre width (265mm), which means the sidewall height has 119.25 mm. The wheel diameter is R18, which means it fits to a 18 inch/457.2mm diameter wheel. The total circumference of the tyre is 2185.61 mm, which is very similar to 225/70 R15(2186.55 mm), 265/40 R19(2182.15 mm), 235/45 R19(2180.58 mm), 215/55 R18(2179.32 mm), 265/35 R20(2178.69 mm), 275/30 R21(2194.09 mm), 195/80 R15(2177.12 mm).
