What to do with my old tyres/wheels off my car?

I brought new alloy wheels and tyres for my car. I took off the old tyres/wheels and now have four wheels with tyres and trims sitting in my garage. I've tried selling all four on ebay for �20 but no one brought them, two of the tyres are new and the other two a month old but still no one wants them! Who would take these off my hands?
