I think it's to do with the clearance needed for the bigger brakes on the vz3 you don't get a spare which is a shame. My old shape has a subwoofer and spare. I'd rather have the bigger brakes though tbh
I did wonder whether it was like the
Cupra Ateca where the back wheel won't fit on the front or something, so they swap the wheels around with a flat. But at that stage I'd give up.
Are we saying the floor plain is different on the VZ3 like a 4drive. Perhaps you just get a grubby wheel in the boot if it doesn't fit but that's sort of like a skinny 🫣.
A bit of a drive not to have spares these days in anycase, although it leaves you vulnerable to buy something to fit if away In an emergency.
