CTIS [Central Tyre Inflation System]

TractAir are official distributors for PTG Central Tyre Inflation Systems (CTIS).

Tyre pressures are critical if you want to get the best from your tractor, trailer or towed implement. Our central tyre pressure control system will save fuel, minimise ground compaction and reduce tyre wear by allowing you to maintain the correct tyre pressures for varying loads, field conditions and speeds. This is all possible on the move at the touch of a button due to a separate CTIS control unit or on the tractor display using ISObus.

In the field, low pressures are needed to spread the weight of the machine and to maximise grip. Conversely on the road higher pressures are needed to give stability, fuel efficiency and minimise tyre wear. Available for tractors, trailers, combines, sprayers, forage harvesters – in fact anything with wheels.

The PTG system is designed and made in Germany specifically for agricultural machines. The system uses only the best quality components and we offer full spares and support from our base in the UK.
