Moin, after my standard tyres the profile slowly gets worse I would like to get a set of new tyres. Currently I have M+S tyres on it, G500 BJ 2015, special model “Edition 35” size 265/60 R18 110H my Mercedes dealer proposes me Conti 4×4 winter contact of the same size. is planned for the next years also a winter Sweden tour, for the summer I would prefer to get tyres with more profile e.g. AT on an extra set of rims. My questions: 1) Has e iner already experience with the tire? 2) the dealer says that I would be bound to the size, since it is explicitly entered in my papers, other sizes (e.g. 16′ would not be possible due to exhaust gas values..? 3) he sells only tires with the snowflake+mountain symbol… to all year round tires he proposes Pirelli… in the search function some swear on winter tires, others are satisfied with MS tires…
