Hi, you can officially use the following size steel wheel:
5.5J x 15".
4 x 100 (this means 4 nuts with 100mm spacing) with 56mm centre hole dimension. (Correct centre hole size is important to fit the hub properly).
ET45 (This is German Einpresstiefe which means the depth of the wheel).
Tyre size is 175/65R15.
The only other manufacturer I know of with this wheel size other than Honda is the BMW Mini One. I doubt the Renault wheels will be correct.
This is the only other wheel size which is approved by Honda for the GE Jazz other than your original 16" alloys, and both sizes can be fitted 100% no problem (obviously not mixing together!) despite what the odd person has commented. The two sizes are written in the handbook as well.
You can use the nuts from the alloys to fit the steel wheels, however don't fit steel wheel nuts to fit alloys, they are harder and can damage the alloys.
Hope this helps.
p.s. Maybe Culzean wrote that because on the topic of all season tyres (currently one post further down) you seemed to know quite a lot about winter tyres and wheels thus not looking like a "non-technical" elderly person!
