Ensure Proper Tire Inflation With Just a Glance
With just a glance, the Cat’s Eye tire pressure monitoring system makes it easy to see if your dual tires are underinflated. The Cat’s Eye system also ensures tire pressure is equalized between dual tires – reducing drag and the chance for a blowout. According to Goodyear, underinflation is the #1 cause of tire failure. If the pressure in your duals is not the same, the diameter of the tires will differ. Since duals are bolted together, the smaller tire will be dragged. With just a 5% difference in PSI, the smaller tire will be dragged 13 feet every mile.
The patented design of the Cat’s Eye tire pressure monitoring system allows drivers and fleet maintenance managers to quickly and easily see if there is a potential safety hazard from underinflated tires. The bright yellow “eye” opens up slightly if dual tire pressure falls below the recommended pressure setting. When the eye is completely open, the pressure has dropped significantly and needs immediate attention.
The single airing point of Cat’s Eye tire pressure monitoring system fills both tires at once and allows air transfer from one tire to the other, equalizing the pressure in both tires. An internal check valve provides added safety by preventing both tires from going flat in the event of a leak, a blow out or when one of the pressure hoses is cut or broken.

1 Check Point
The yellow eye allows drivers to quickly see if there is a potential safety hazard from underinflated tires. The eye is designed to remain closed within the correct operating pressure range of your tire and open when underinflated.

Tire Pressure Equalization
The system equalizes air pressure between dual tires for evenly distributed load pressure and tire wear. The equalization improves handling and braking. Tire scrub and cupping are greatly reduced on uneven roads.
