The COTON GRAND 24 tyre pressure tester is one of the best machines of its kind on the market. It is used to find tyre defects such as bulges, punctures, cuts and all kinds of damage to the cords and beads in a fast and efficient manner. With a bit of practice, it is possible to examine a tyre with it in just over a minute, while being protected from the consequences of an unexpected burst of an inflated tyre.

Unlike tyre-examining machines up to a maximum of 22 inches, it has a chain-geared motor for rotating the tyre to be examined, activated by a foot switch (pedal) or a switch on top of the machine (both options included). It is activated by a foot switch (pedal). All this makes this tyre tester simply indispensable in tyre garages, storing facilities and tyre retreading centres.

The machine is suitable for examining tyres removed from 13-24 inch rims, and a set of locking latches (pawls) allows tyres of any width to be mounted on it. The kit comes with three pairs of discs for different sizes:

  • Pair 1: sizes 13-16 inches,
  • Pair 2: sizes 17-20 inches,
  • Pair 3: sizes 21-24 inches.

This machine is designed for customers who mainly examine tyres over 22 inches. This is because adding the ability to put such large tyres on the machine requires the use of a larger ram, which moves slower than in other models.

In order to start working on this tyre tester, it needs to be connected to an average capacity air compressor (main power supply) and an electrical outlet (motor power supply). The control itself, on the other hand, is comfortable and intuitive and is carried out by means of levers located on both sides of the machine.

An optional roof with lighting is also offered at an additional cost.
