Cat's Eye Dual Tire Pressure Maintenance System
Easy to see tire Inflation from greater distance than the
Tire air pressure has a significant impact on gas mileage.
According to the US Department of Energy and the EPA, gas mileage decreases by about 0.4% for each ONE psi drop in tire pressure. So if your tires are 10 psi low, your gas mileage will decrease by 4%. If you are getting 25 miles per gallon (mpg), that 4% translates into a 1 mpg loss.
For every 1 psi of air lost, a tire loses 60 to 70 pounds of load carrying capacity. Slightly Low pressure also causes increased tire wear, at the outer edges of the tread. More severe tire pressure loss causes increased flexing and heating of the tire side walls, which can lead to catastrophic tire failure (Blow Out).
Tire pressure decreases as air leaks out slowly over time, and also varies with temperature. For every 10 degrees of tire temperature change, there is typically a change of one psi of pressure.

We recommend the Braided Stainless Hoses due to their greater resistance to UV, abrasion, road hazards,
and better appearance.

Installation / Operation Tips:
The torque limit on the Cat’s Eye bracket mounting bolt is 15 FT-LBS.
Damage or leaks can occur if mounting bolt is over tightened.
Cat's Eye System Recommends installation under "High-Torque" lug Nuts or Hub Bolts;
Not Recommended for installation under "Low-Torque" Simulator Jam Nuts.
If you have wheel simulator covers or plastic wheel liners or plastic center caps, this system may not work unless you remove or modify them to gain access to high torque nuts.
Install hoses with minimum bending and kinking.
Seals must be replaced after the second removal of the cat's eye hoses from valve stems.
Valve Stems must be in good Condition to avoid leaks,
Check for burrs that could damage the seal.
Bubble Test with Soapy water to insure no leaks and correct installation
The most common installation problem is over-tightening the hoses.
Only install hoses hand-tight plus one-half turn.
Over-tightening will damage the seals. Seals are available in the parts list below.
Do Not use Acid Wheel Wash, this will void the Cat's Eye Warranty.
When installing new or used Tires, the inside of the tire must be free of all materials, including wheel balancing compounds.
Cat's Eye is NOT Recommended for Steer Axles.
Tire Pressure is Too Important to Neglect:
Cat's Eye Tire Pressure Equalizing systems Reduce Risk of Tire Failure and
Increase Miles Per Gallon.
• Improve Tread Life - With as little as 20% under-inflation, tire tread life is reduced by 25%. When tires are maintained at an accurate inflation value, their tread will last longer.
• Reduce Maintenance Costs & Downtime - Statistics show that 90% of all tire failures are a result of under-inflation and almost 50% of all fleet emergency road-side assistance calls are attributed to tires. Accurate and consistent tire inflation can significantly reduce vehicle downtime and overall fleet maintenance costs.
• Improve Fuel Economy - Tires operated at 20% under-inflation will reduce a vehicle's fuel mileage by 2%. Considering that 56% of all commercial vehicle tires are under-inflated and that the combined mileage of a bus fleet is millions of miles per year, a 2% fuel savings represents a significant cost savings to any fleet's bottom line.
• Improve Dual Wheel Assembly Performance - When one tire of a dual wheel assembly has a lower inflation pressure than the other, its circumference is smaller than the tire next to it resulting in improper axle weight distribution and wheel drag. This condition rapidly generates heat that destroys the tire's integrity and creates the environment for catastrophic tire failures. Proper dual wheel inflation will result in better tire life and a safer trip for the driver, passengers, and vehicle.

Tire Manufacturers Agree: a primary cause of early tire breakdown and poor tread life is under-inflation. Low tire pressure not only causes excessive heat build-up in the tire, creating dangerous driving conditions, but also shortens tire life. Unwanted heat will rapidly increase tread-wear and can tear down retreads and destroy tire casings. As much as 90% of all tire breakdowns is the direct result of tire under-inflation.
Tire Valves use International Standard threads. The standard Schrader Tire valve has the following thread: 7.7 mm OD, 32 tpi, or 0.794 mm pitch, Minor diameter is 6.9mm, Thread designation is .305-32 or 7.7-32
We have had customers with leakage problems that turned out to be related to inadequate valve stems. Quality Valve Stems are much more critical with high-pressure truck tires than auto tires.
