Hello, my wife drives a 2018 SEAT IBIZA. Lat registration certificate 1 at 15.1 and 15.2 she is allowed to drive 185/65 R15 88H tyres. These are also mounted on the factory side as summer tires. Now she wanted to change to all-year tires and keep the original rim. Speak only new tires. (Online) she bought all-weather tyres M+S (Michelin). When this should be installed the dealer said that these should not be assembled (trader and assembly is the same shop as o no conflict of interest). He gave my wife, it MUST be 185/65 R15 91V. Why a car with ~90PS tires needs the 240km/h can, and all weather tires now have to have more load than the normal I really don’t understand now… The COC is currently not findable, so I could not look there yet. Therefore I can only ask general questions: – Can it be that the values in 15 registered values do NOT apply to all-year tires? Thank you and greetings!
