My Mk3 EX Jazz came with Alloys, fitted with 185/60-H15 tyres
I am using a standard steel spare wheel from an earlier Jazz fitted with a 175/65-H15 tyre. and heavily plastered with 50MPH Max labels
The rolling diameter is virtually the same so there is no affect on the speedo reading or the low pressure tyre warning system, although you may have to recalibrate it
I can assure you that the Mk3 wheel well will accommodate this wheel assembly. but it is necessary to add some support to the boot floor, if you intend to carry heavy objects.
