The wax is there for when the tyre is stationary. It migrates from within the sidewall compound to the outside surface and forms a layer there to prevent ozone attack. The other chemicals and the carbon black that are used prevent attack by UV light as well as preventing cracking due to the sidewall flexing when moving.

If your car tyres are over 7 years old, pay attention to the sidewalls and the fact that they WILL be automatic MoT failures.
Then Avon rubbish cracked so bad after 18 months they were binned with no wear as such, perhaps they were ozone hollics?
Not sure what the Toyota had, one year jacked up in the sun and springs were coming out of the sidewalls. Plus it was not an old car.

Plus there is no alternative. Plus as they have never been used in 20 years I am not intending to source alternatives at insane prices which I suspect will be no better than the existing ones, and most like will also never used.

or was it the year before?) for passenger vehicles. It changes later this year for front tyres on commercial vehicles, trucks and buses.Personally, I have a thing about space saver tyres. I hate the very idea of them because they are so skinny and need high inflation pressures to compensate for the weight they have to carry. This makes them dangerous imho if you exceed the 50mph/80kph speed limit imposed when using one of them.
IF I ever had a car with a space save in the boot, I'd go straight to KwikFit or Halfords and buy a suitable rim and a proper tyre and put THAT in my boot. The corresponding increase in total vehicle weight is at most 3 or 4kg so, the negative effect on fuel consumption is marginal to say the least.
Our new Qashqai doesn't even have a space saver spare. All there is is a pressurised can of gloop and a 12v inflator.

My car has different width tyres on the front to the back, for you, that means buying two new wheels and tyres from Halfords, very commendable even if they sold them, but as the boot will not take one standard tyre let alone two, where are you intending to put two?
This brings me back to my original question, can you post the link where it confirms that I would be breaking the law using a space-saver for the purpose intended.
My other car has a huge boot so I do keep a new wheel and tyre in that even if it weighs a ton. Afraid the tyre is one direction rotational, so guess I might break the law with that.
