I can't find anyone selling 4-hole with a PCD less than 100mm. There
appears to be a 3-hole size that is 88.5mm, but obviously that is no
good either. The tyre and tube are fairly easy to get hold of, but few
places will repair a punctured tube, so I could do with having a spare
about the place.

Tubes can be repaired with a bicycle puncture kit.
