With the tyre maybe the cloner will work if you model it another scene on it's own (may you did this?). Make sure to enable the "render instance" option as this will greatly reduce the load on your computer. When you're happy with it, make a copy and then make the copy editable so that the cloner is no longer being used. Copy this tyre into main scene.
Alternatively and this has worked well for me is to use Sub Polygon displacement for the tyre using a displacement map. Attached is what I mean where the grooves in the tyre are generated from a displacement map applied to a smooth tyre. However if the tyres are chunky like a motocross tyre then physically modelling is best. I created the displacement map in a vector drawing program.
