I thought they were smaller?

If you want one I have a spare going free as I changed it for a full size road wheel with matching tyre as mine are bigger than stock. 2012 TDV8 Vogue (L322)

Cheers for the offer, but I have a full sized spare. It’s mismatched to my wheels, and planned to change it to match… but now I’m looking to change from 45 profile to 40, so I’m waiting to save my pocket money for those.
I’m also looking at the Pirelli all season zeros which are about 300 a corner…

The last space saver I see was for my Audi Q7 and that was smaller… but as I think about it, it needed to be inflated. I never used it so have no experience of it. Currently driving: 2012 L322 SE Overfinch 4.4 tdv8

The space saver on the Audi is indeed different and expands to full size and not possible to have a full size matching road wheel spare on those cars. 2012 TDV8 Vogue (L322)

Space savers, whilst usually being smaller diameter and narrower than the road wheels, have a tyre size and aspect ratio which effectively gives it the same rolling diameter as the standard road wheels. 2021 D350 Fifty Edition - Carpathian Grey

If you run different sizes across an axle you will cause problems as highlighted by a recent thread in that if the ECU detects more than a 1kph difference on wheels it will interpret this as cornering and change gearbox behaviour I.e stop it changing up. Not sure different tyre sizes across an axle will pass an MOT either. If anyone has done the popular mod of fitting larger 255/55 R20 tyres from the L405 they will find themselves in this position if they have to use the spare which is a very good reason to replace it with a full size spare. As for diff wear I’d think the amount of time over the life of a car that it spends cornering or driving on non straight roads let alone the off road design would mean the diffs are pretty robust - but I wouldn’t want to test that assumption by running different size wheels.

Should be fine to get to a garage a short distance away just like a space saver. 2012 TDV8 Vogue (L322)
