COTON COT-3 pneumatic tyre tripling machine - front view

A COT-3 pneumatic tyre tripling machine is used for doubling tyres (packing them one inside the other). With this brilliant machine you can easily load around 3000-3200 tyres into a 40ft container, which lowers the shipping cost even by two thirds.

It is perfect for making 3 or 4-tyre packs, but can make packs of 6 tyres or more. When used properly the tyre tripling machine is safe both for the operator and for the tyres. Similarly to COT-2 it is powered by compressed air only so there is no risk of electrocution.

We do not make COT-3 anymore but we still offer spare parts for it. It was replaced by COT-10.

1. The table of the machine can fit a car, jeep or commercial tyre with a maximum diameter of 22 inches;
2. The outer tyre must be the same or larger in diameter than the inner tyre (e.g. 16″ –> 16″, 18″ –> 17″).
3. Any tyre that is less than 15 inches in diameter will need to be the last tyre in the pack (the tyre in the very center of the pack). It is impossible to fit another tyre into a 14-inch or smaller tyre because the jaws would be too close together and the vertical pusher would not fit between them;
4. The width of each tyre into which another tyre is inserted must be at least 10 mm larger than the tyre being inserted (e.g. 215 –> 205).



There are poor quality Chinese copies of our original machines available on the market. We strongly advise against buying them because they do not comply with EU safety requirements and in case of an inspection the buyer may be fined by the supervisory authority in the country concerned.
