If you stay with the same outer diameter there will be a slight difference

You need to go down in tyre profile and there will be a smaller height of
rubber that could move around - you get increased stability
This is why the sportscars go with 18 inch wheels with almost no rubber
height !
The drawback is less air between rim and ground with a bumpy ride as a
result
