This was the scene off Altcar Lane a few days ago:-
If I have read the situation here correctly these tyres have been taken out of the drainage ditch that runs alongside Altcar Lane during maintenance of the ditch.
Used tyres seem to be dumped in ditches all over Sefton Borough and indeed all over everywhere. I’m guessing that’s to avoid the cost of them being disposed of properly. Surely there has to be a process devised so that the fly-tippers can be traced as you would be hard pressed to find a roadside ditch without tyres in it these days.
