Tires: Wheel replacement, alloy wheel, steel wheel

Question
Not strictly speaking about tyresn (but no section on wheels) but I have an alloy wheel on an older car that is causing a slow release of air around the rim.  Short term I thought I would replace it with a normal steel wheel (5Jx14 ET45) which I have available while I run repairs on the wheel.  Would this cause any problems ?  The steel wheel is heavier and not sure if this could affect the cars stability ?

Probably a daft question, but can't find any reference.  Do you know if there are any discussion groups for this sort of question ?

Thanks for your time

Answer
Richard,

This gets more into how the suspension and vehicle are going to react.  I don't think it will have much of an effect, and since it is temporary, I think this is a good solution, so long as the wheel is more or less that same (width, offset) as the alloy wheel.

Hope this helps.
