Where do you store your tyres n rims?

[Dudders]

I've got a fair collection of rim/tyres/foam all floating around in a Caster box draw.

Being anal I try to keep them all in pairs depending on wear, foams or cuts etc.

Has any bright spark found a brilliant solution to stop them wandering about in the draw?.

Like I said, I might be anal but I like to be tidy and organised!!!
