Tyre storage - Looking for recommendations

Hey folks,

Does anyone have any recommendations for a 'tyre hotel' / tyre storage place that will store your tyres between seasonal swaps?

I know a certain, well known, tyre fitter that does it but I'd rather not have tyres fitted by them and they'll only store tyres purchased from them.
I don't mind buying tyres from the same place that stores them but I'd rather cowboys didn't fit my tyres on my nice new alloys.

I'm in the Glasgow area. All suggestions and recommendations appreciated.

Thanks!
