The bright yellow "eye" of the Cat's Eye, opens up slightly if dual tire pressure falls 5-6% below the recommended pressure setting. When the eye is completely open, the pressure has dropped 10-12% under the recommended pressure and needs immediate attention. The internal check valve prevents both tires from going flat in the event one tire develops a leak, blows out or when one of the pressure hoses is cut or broken.
Cat's Eye is available with rubber or stainless steel hoses in lengths of 12", 14" or standard 16".
The chart belows shows how to properly read the Cat's Eye indicator.
With just a glance, dual tire pressures can be checked on efficient walk-arounds with the Cat's Eye® Tire Pressure Maintenance System.
The Cat's Eye makes it easy to see if your tires are underinflated. This system attaches to the dual's hub or lug bolt and allows air transfer from one tire to the other. Its single airing point fills both tires at once, making the job quick, clean and easy. With just a glance, you'll instantly see changes in tire pressure.
