Michelin has unveiled the ALPIN 7 winter tyre, featuring an advanced tread design with additional sipes and an evolving tread pattern to maintain traction as the tyre wears. The new model aims to enhance braking and acceleration on snowy and wet roads while improving overall efficiency for a variety of vehicles. Unlike the Alpin 6, which was considered a bit overpriced for its performance, the Alpin 7 is expected to offer better value and address concerns in upcoming winter tests.
215/60 R18 doesn't belong to the most popular dimensions for winter tyres - there are 1 tyre models available, which can be compared to 155/60 R15, 170/60 R17, 160/60 R14. Let's break down the sizing - 60 is height of the tyre, which is calculated as 60% of the tyre width (215mm), which means the sidewall height has 129 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 2246.87 mm, which is very similar to 235/55 R18(2248.44 mm), 295/35 R20(2244.67 mm), 205/75 R16(2242.78 mm), 235/60 R17(2242.47 mm), 235/50 R19(2254.41 mm), 265/30 R22(2255.04 mm), 255/45 R19(2237.13 mm). There are multiple speed indexes available for winter tyres in 215/60 R18: H(210km/h), R(170km/h), T(190km/h), V(240km/h). The same goes for weight indexes: 98, 102.
