    Hi,

    Went to pop the spare wheel on the car and the bolts don’t seem to want to reach the thread.
    The car has non standard 19” wheels.
    With correct Merc bolts inc security ones.

    Spare must have a “deeper/thicker” hub.

    Bolts only protrude about 10mm

    How far should they protrude?

    Going to have to buy x5 spares for the spare.....( not in the boot with spare as they are on the A-class)

    Only found out as the brand new tyre fitted yesterday was on the rim, took wheel back and it’s a duff bead on the tyre leaking, manufacture fault.
    (And in off to work back Saturday....they need to order new one in)
    So haven’t got the wheel to check ‘protrusion’ of the current set up.

    Call me Carlos :confused:

    10mm should be plenty of thread, ideally 5 turns

    I would have said 10mm sticking out the back of the wheel is to little, more like 20mm, as the disk portion of the hub isnt threaded.

    I have just checked, the 215 has the same bolts for the spare wheel as the standard bolts, so it must be that your aftermarket wheel's have a thinner hub and therefore shorter bolts than standard.

    My spare wheel has different bolts with it , because it's steel as opposed to the normal alloys .
