I have an old Volkswagen Golf 4, 1.4. The size of the summer tires is 195/65 R15.
When I bought the car it came with a set of mounted 205/55 R16 winter tires.
When I took the car to a mechanic to have the wheels changed, he told me that the winter wheels are not compatible with my car.
Is this possible? Do the wheels have to be of the same size?
UPDATE: thanks a lot for your answer. Unfortunately I cannot comment under 50 reputation. How can I tell from looking at the wheels whether or not the bolt patterns match?
