Couldn't believe my eyes!

Advertise them cheap on local Gumtree - "Buyer collects"

They make good planters!

Air compressors cost a lot of money and I'd be wondering why it had been abandoned on your drive. Maybe a quick call to the local police to see if they've received any reports of one being stolen before you do anything about getting rid of it?

They may have been delivered to the wrong house.
Check first.
A friend of mine got home from work one day to find BMW on her drive, when she got inside ,the keys were through her letterbox.
The garage had arranged to do this for a customer.
Only problem was it was the right house number on the wrong road.

If supermarkets deliver someone else's order by mistake you keep it as they're not allowed to take it back. I wonder if it's the same for cars?

Are they new tyres, chicken? Were they delivered by mistake or old ones just dumped?
I wouldn't try to dispose of them, you could advertise on your area's local FB page and ask.

Or yes, they do make good planters.

Seems odd that they just appeared overnight though? And if it was a bona fide delivery, albeit to the wrong address, surely the tyres would have been neatly stacked up, not placed in a line, down the drive?

We had an engine dumped in the middle of our farm gateway (we couldn't get in or out of our property.
The council refused to remove it for us because it was on 'private land' so therefor wasn't their problem, it seems that if it'd been dumped on the grass verge it would have been 'fly tipping' and they'd have moved it for us.
(Is there a way of posting photos on here?)

Sounds like a fly tipper jealous of your long driveway. It costs money to take tyres to our recycling plant so dumping them on your driveway, job done and probably not overlooked. Personally I hate all fly tippers. They have total disregard for our countryside, the people who have to come and clear it away and the taxpayers who foot the bill.

Phone any local equestrian places as they use them for horse jumps.

The owner of the land it's tipped on pays the bill - unless its actually tipped on the public highway it's not the council's responsibility.
At least that's what they told us -someone came out, looked at it and told us it wasn't their problem.
So helpful!

Yes re photos. Go to this

Chicken - did you find out anything more about this? What have you done with the stuff?
