Hello, I have today quite spontaneously hit with a Lodgy Prestige dCi 110 (Vfw, 3tkm old). This is still on the 16″-alu with summer tires. But now I still need winter tires… – do I need other wheel nuts for 15″-steel rims? – can I then use a 16″-alu wheel as a spare wheel (roll-off circumference, space for the wheel in the trunk)? At the moment is only the repair kit on board. – from other Dacia (possibly even Renault?) also rims fit?
