extremely dodgy to drive any real distance on one of those space saver wheels... don't forget it not just how long they last for which you have to think of.
They affect overall grip and stability - especially when cornerning and should only be used to get you to the nearest tyre fitter.

I once had a R33 GTT try to play on the M40. He was behind me and sliding all over the place! I let him by to see him race off at 90+ with a space saver on the back.
Totally unsafe, I expect he was in the crash barrier a few miles up the road as he could hardly keep it in a straight line.

Ive driven halfway across France and back to Derbyshire on a spacesaver. Its a normal tyre with a suitable load rating, so why every would it 'burn out'?

We went a good deal over 55mph/90kph! Also, the car sat on that spacesaver for almost a year and was then driven another 500+ miles before new tyres were fitted.

What is the law regarding running a car on spares ?
I mean the law states that you must carry a spare. So what happens when you use the spare ? Are you limited to a certain amount of miles, as you no longer have a spare ?

Bizarrely if you are carrying one it must be in good condition / road legal and would fail your an MoT if it wasn't however if you put it in for a MoT without the spare in the car it will pass.

There's no law to say you must carry a spare. Some BMWs have run flat tyres and as a result have no spare.

In the Britain, carrying a spare tyre is not a legal requirement. Whilst a spare tyre is not being used and is stowed away there is also no legal requirement for it to comply with normal tyre . If a wheel or tyre needs changing, for instance if a puncture occurs, and the spare tyre is fitted, then it must comply by

Technically you can drive on it as far as you like so long as it has a legal amount of tread.
Practically, you will die of boredom long before that point is reached.

It wont burn out. The speed limit is probably there in case something happens in front of you. I wouldn't like to swerve at high speeds with a wheel that skinny on my car. I doubt the car would respond that well!

Load/speed rating I think is the main issue: What happens to a T-rated tyre (110mph) if you drive constantly at 150mph....it will eventually tear itself apart and you have a blow out.
Space saver tyres are usually rated at M which is 80mph max. HOWEVER, they also have reduced load index ratings (around 99), which means they cannot sustain their max speed under heavy loadings (which is why they have 60psi in them). This means that the vehicle's weight will reduce the max speed capability of the tyre.
Note that some cars have standard spare wheels (notably older BMWs), but are a smaller diameter and narrower wheel with a normal standard profile tyre (but different to the normal wheels), these rarely have any max speed warnings (barring the physical rating on the tyre). So if it was just about handling and control, these tyres would also have warning stickers.
In the end of the day the max speed label on the wheel is for safety. If the manufacturer thought it was safer to go faster, it would say so.
Maximum distance at this rated speed (56mph), should in theory be indefinite.
Also bear in mind the words "temporary use". It is against the law to have a vehicle with two different size tyres/wheels on the same axle. So you may get a defect notice if you get stopped by plod (a defect notice is to make sure your not driving round on it all the time, and lie about its "temporary usage")..

Having had to drive on a space saver i'd say the 50mph limit is for handling safety more than for it blowing apart. They don't have much grip and depending where it's fitted you might get some funny handling.
It'll be ok to drive if you're desperate but much better to get it replaced after your interview before you drive it back.
