When Sportauto tested examined five brands of size 215/40 R18 summer tyres earlier this year, it tested them alongside an all-season model. This premium all-season product struggled against the summer tyres in temperatures well above the 20-degree mark, leading the motoring publication to conclude that “the all-season tyre is just a compromise” in summer conditions, especially when paired with sport cars such as the Hyundai i20 N it used for testing. Sportauto still holds this opinion, but it has now decided to test six of these “compromise” tyres – again in size 215/40 R18 – to answer a couple of important questions.
