Hi people, I’ve had the last one every now and then when braking with my Opel Vectra B a rather uneven brake (almost a stuttering) which became worse and worse the last days. When I was at the tank today to refuel air, much to me on which the valves were not there where they should be. But a few centimeters further had slipped so the valves had already folded off. Since I already put on winter tires soon I want to ask if the summer tires now any he could be damaged and should I have the tires restocked before winter?
