Got a flat. A simple swap, but the spare has 50MPH stickers on it.

So why would the spare wheel have a maximum speed limit of 50MPH on it
when it has the same sized tyre on it as the flat one? The only
difference I can see is that the spare is not an alloy wheel.

It's a space saver. Narrower width, smaller diameter and maybe even thinner carcase. Although it may not be obvious, it IS lighter/thinner/weaker than a *real* spare tyre
