A spare wheel is a
must for me, too.
I've just taken a punt on an 18" "
Formentor" space saver on Ebay (although my wheels are 19" - I've read that one inch makes no difference in an emergency) and a VW stylee retaining screw (don't know if it will fit, but it's Amazon, so it gets returned if necessary).
The wheel is for pre-facelift Formentors, so I'm also assuming that the stud size & pattern didn't change when they introduced my version, the facelift.
£139 for the wheel and £12.99 for the screw. Thanks to this thread I'm aware that a front puncture would involve a bit of wheel-swapping because of the Brembos, but anything's better than squirting gunk into an expensive tyre that might still be useable.
I'll let you know how I get on. Fingers crossed.
WHEEL NUT GREASE
As an aside, does anyone know why Cupra's Owners Manual states that you must
not grease the wheel nuts? I'm old, so I always put a bit of copper ease on my nuts. Is this wrong?
