Hiya Dave,
In my opinion!
Any 4x98 / 4x100- 15" to 17" 6-8 inches wheels can be fitted to the B as long as the offset lies between 30 to 40 max.
Of course this is not without some slight modifications depending, ie , spacers and spigot rings and wobbly bolts if using a 4x100 stud. depending on brand of wheels.
If i'm not mistaken, the standard B rims are a 4x98 bore 15"x6.5 with a 32 offset.
Its looks like the punto wheels you have shown list a thinner 6 inch wheel -45 offset. meaning the wheels would sit further in on the hub by 13mm than the standard. If the bore is not 4x98 and is 4x100
and you really want to fit these wheels you would need extended wobbly bolts, a 13mm upwards spacer to compensate, so maybe a 15mm spacer would create the same look or 20mm to slightly widen the track and possibly even new spigot rings.
The bigger size of 16" is not an issue.
Hope this helps.
