Tire Pressure Monitoring

Under inflation is the number one cause of tire failure according to Goodyear. Improper tire inflation can also lead to low mile per gallon and increase the risk of a blowout. Tire Pressure monitoring systems are a cost effective way to notice if there is an unsafe change in your tire pressure. At a glance you can see if your tires are underinflated.

Tire Pressure Monitoring

Tire under-inflation is the leading cause of premature tire failure. Even though checking and adding air is a simple task, it can be time-consuming. It is easy to talk yourself out of checking air pressures on all 24 tires of an 8-axle trailer in the middle of winter. The Link Cat’s Eye TPMS offers a convenient way to check the pressures visually and fill both duals from a single point. The easy to see Cat’s Eye dome gives a visual confirmation that your tires are at the correct pressure or that they need attention, so you only spend time checking the tires that need it.

Full Taper Leaf Spring

Each Cat’s Eye assembly is set for a certain PSI rating and this should match the PSI that is being run in your tires. When the Cat’s Eye dome has completely closed the set of dual tires that the Cat’s Eye is attached to are at the correct set pressure. If the eye is slightly open the tires are slightly below pressure and as the eye opens more it is a signal that the tires are severely underinflated. If the eye is at any position besides fully closed the tires should be checked and the pressure adjusted.

Besides making the checking and filling of your tires more convenient, the Cat’s Eye system also helps extend the life of dual tires by equalizing the pressures between them. A 5% difference in air pressure can cause the lower pressure dual tire to be dragged 13 feet every mile. This drastically shortens tire life by causing wear and generating heat. The extra resistance causes higher fuel costs by lowering MPG and the heat can cause blowouts.

When choosing a set of Cat’s Eye TPMS there are some options that should be considered.

  • Tire Pressure – Pre-set pressure range from 60 psi up to 130 psi. This pressure is factory set and stamped in the back of the housing for the Eye. The pressure cannot be changed
  • Wheel Size – The wheel size will determine the hose length that is needed to reach from the valve stems of both duals to the location that you will mount the Cat’s Eye housing. Hoses come in 12”, 14”, and 16”.
    • 12” Duals – Typically used with 17.5” wheel and tire
    • 14” Duals – Typically used with 19.5” wheel and tire
    • 16” Duals– Typically used with 22.5” and 24.5” wheel and tire.
    • Super singles - All kits will all use 12” hoses since they only need to reach one valve stem per wheel.
  • Hose Material - Cat’s Eye systems have the option for stainless steel hoses and rubber hoses. The hose material will not change how the kits function. Stainless steel is a premium option that is more resistant to impact and abrasion.

Installing the Cat’s Eye system is easy and can be accomplished with only hand tools.

  • Confirm that Dual valve stems are 180° apart
  • Inflate both tires to the correct PSI
  • Brackets for both Hub mount and Wheel mount are included with each kit. Hub mount brackets will mount to the hub cap or the axle flange. Wheel mounts will mount against the rim with a lug nut.
  • Attach hoses – The inside tire will use the straight fitting and should be connected first. The 180° hose will attach to the outside tire. Finger tighten and then use a wrench to tighten 1⁄2 turn.
  • Inflate tires through the Cat’s eye inflation port and confirm that the eye closes.
  • Check pressure at the inflation point.
  • Spray all fittings with soapy water to ensure there are no air leaks.

The Cat’s Eye Tire Pressure Monitoring System is an easy way to monitor your tire pressures any time you do a walkaround of your truck and trailer. The system is cost-effective with an average return on investment in 3-6 months and easy to self-install.
