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

Having a problem with the words "same sized tyre"?

The tyres on the car and the spare all say 195/65R15.


Is it the same weight? There has to be a reason for the 50mph sticker. If
the size is the same then that only leaves weight/thickness or possibly
speed rating as the remaining option. Have you checked the speed rating
on
the tyre wall?
No doubt just penny pinching by the car makers.

Nothing wrong with that. How often d'ye need a spare wheel, these days.
Last time I needed one was in Whitstable in 2014. Time before that was
probably in 1984 or so.

While I went a long time between flats, recently I went through
a patch where I got a couple a year for a few years. Almost always
due to a screw through the tread, in one case two screws almost
189 degrees apart so it couldnt be sabotage. We do have a lot of
new houses being built so likely they are coming off builders utes etc.
