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.
