we ve just priced a job for an office building and on the specs the footing is to be made from old car tyres and limestone compacted, i was just wondering if anyone else has come across this method, any tips or advice
tyre foundation

Sounds novel...presumably it's a limecrete foundation and the tyres are a) to provide formwork and b) weather protection while the foundation is curing.
The curing will take an age, especially in the winter months.
Makes me wonder what the rest of the construction is: obviously an uber-green project with an architect in brown cords and hush puppies, grey beard and a panama hat. And mad, mad clients, who will never be happy, who will know more than you about every facet of the job, as they've read up about it all on a website or several.
One to steer a wide berth from methinks

it s not limecrete just compacted limestone actually around the tyres does nt make sense to me either but those crazy architects are we known for massaging there ego s from time to time. the rest of project consists of a timber framed building cladded with 50 mm stone slips, solar panels and a wind turbine(which as we al know will take about 200 years just to pay for its self)

Ah, so I was most of the way there, then.
Why compacted limestone? Not very "green": environmental impact through excavation, transportation, yadayada. Could have used graded type 2 from reclaimed materials, for example.
They've clearly gone off on one....

the consensus is that it's it's either too green or not green enough then?
i assume that the limestone is to be compacted inside the tyres? in which case i would say that the car tyres would nicely contain the tendency of the stone to spread if it's not bound together with cement and steel reinforcement . a neat solution. just make sure the limestone is well compacted in layers.
of course if the idea of innovation is scary we could all go back to living in caves.
Why not just dig a shallow trench and put compacted type 2 in it then?
I'm all for innovation, but doing things "differently" just for the hell of it and under a supposed "green" banner too serves...what purpose exactly?

i don't think the sides of a trench would offer the same restraint to the stone spreading as a steel reinforced car tire, but if it was compacted properly and deep and wide enough to spread the load it would work to a certain extent. similar principle to how vibro flotation (aka stone columns or stone piles) work to improve ground.
