Once minis started getting alloy wheels the spare was still a 12in steel wheel with a 145/70 tyre. They were then marked with 80kph or 50mph when installed due to the different wheel/ tyre size on an axle when in use. So effectively a space saver for the 13 inch shod MPi.
So you just need to pick up a 12in steel wheel fit a 145/70 tyre and you have a useable spare that will fit in the wheel well. And yes the wheel will fit fully inflated and ready to go. Put 30psi pressure.

That sounds great, Do you know if the wheel studs will fit the steel as well as the alloy or will I need to carry a spare set of studs?

If the rolling radius is slightly different between the steel 12 inch and the alloy 13 inch, do you think this will affect the way the lsd handles it?

I would swap the front tyre with a rear if burst and put the 'space-saver' on the rear.

My mistake, I meant the wheel nuts.

Doh, its obvious when its pointed out to you, thanks Batmini

Yes, never put different sized rolling diameters across your diff! 

 

If you blow a front tyre, put spare on the back and put a good back one on the front. At the moment I have alloys with different nuts, so I have an extra set of steel wheel nuts in the boot.

^^^ that's not a space saver, it's a standard 12 inch mini steel wheel.

 
I've never seen a space saver for a mini if i'm honest. Mine is a 12" spare wheel.
Yeah, Rover never did a space saver for the mini and there isn't a space saver available for any other car with a 4x4inch pcd.
See Steve220's boot picture, shows figment of spare wheel marked up 80kph as a space saver.

It's not a space saver in the traditional sense though. As in, both the wheel and tyre are the same construction as any mini which came with 12 inch wheels as standard.

I would also treat it as an emergency get you to a garage wheel rather than one to finish your trip on. If you've got a hard to get hold of size tyre then I would consider also having a full spare tyre with you so that whatever garage you find can just switch the tyres over so you can continue with four matching wheels and tyres.

The wheel nuts used on MPi will work with the steel wheel.
You say you have an LSD (limited slip differential), these are not standard fit. If you have an LSD then definitely don't mix the 2 wheels on the front!

This is a really old thread, but I wanted to note that the steel wheel lug nuts ARE available from minispares here as of Nov 2020:

 

http://minispares.co...uts/113087.aspx

 

And they do sound pretty specific as they bothered to note:

 

When the 12" steel wheel was introduced as standard in 1984 they changed the wheel nut seating angle to 60 degrees.

 

Whether that is the same angle as the alloy wheels or not, and whether the alloy lug nuts would hold the steel wheel on well or not, I could not say at the moment, but as I have Rover alloys all around as well as a steel wheel as my spare (with a set of four of the above nuts in my jack bag), the next time I have a wheel off the car, I will offer up the steel wheel with an alloy nut and see what the fitment is like..

A 60┬░seat alloy and a 60┬░ steel will be able to use the same nuts. The issue is surface area, the steel wheel has far less a surface area for the taper face to grip

You could put a steely on the front, just to get you to a safe place to swap wheels about. If you're touring with a mate you could set yourselves up so you could share a pair of steelies to give you an axle set. Carrying a set of wheel nuts wouldn't be a deal breaker, if necessary.

 

You might even find a trailer wheel that's a bit narrower, but it's unlikely it'd be as good for offset.
