Hoarding would be being unable to buy one steel, so buying a set of four alloys as an upgrade, then finding out they had been incorrectly listed and were the wrong size, so buying another set of four, only to discover all the tyres were too poor to fit to a wheelbarrow and in your search for inexpensive tyres, finding a matching set on some wheels for a VW so buying those, leaving you with:

1 spare steel 14
3 good steel 15s
1 bent steel 15
4 14" alloys with tyres
4 15 inch alloys and tyres on the car
4 15 inch VW alloys without tyres

Then chuck the whole lot in the shed and wonder why you have no space.

That's NEVER happened to me....
