What to Do with Tyres
Can trade-in for new tyres.
There are locations where old tires are retread and sold to customers again.
Strips of car tyre rubber make:
- sandals
- shoe soles
- rubber hinges - tough, durable
Whole tyres can be stacked and earth filled to make basic buildings
Tyres can have their treads recut, but the resulting tyre is not safe at high speed, not legal in first world countries, and it takes a fair bit of work to do.
Tyre stacks can be used to multiply the yields of potatoes. When the plant has emerged above ground its partly reburied, and this is repeated several times, adding tyres as necessary. The result is a deep rooted plant giving several times the yield.
The rubber can be remoulded to make other products, but how easy this is I dont know from experience.
Inner tubes can be used as pressurised air tanks. They can be inflated with an old fridge compressor, but there are safety and functionality gotchas that need attention before constructing such compressors.
