Safety Saturday – Nissan’s Tire Pressure Monitoring System

TPMS Highlights –

  • TPMS typically consists of four valve stem/air pressure sensors (transponders), a low tire pressure warning control unit, and an antenna.
  • If a tire’s pressure drops to approximately 26 psi, a warning light graphic on the dash illuminates to alert the driver of low tire pressure.
  • Select vehicles also have Easy-Fill Tire Alert, which enables proper inflation without the need for a tire pressure gauge. Once the right air pressure is reached the horn will honk.

What Is TPMS?

The Tire Pressure Monitoring System (TPMS) alerts the driver to low pressure in any tire. On select Nissan vehicles, the system also includes Easy-Fill Tire Alert, which makes it easy to fill a tire to the correct pressure without the use of a tire pressure gauge.

How It Works

TPMS typically consists of four valve stem/air pressure sensors (transponders), a low tire pressure warning control unit (Body Control Module), and an antenna. A sensor/transponder is integrated with the tire’s valve stem, and transmits a signal, indicating tire pressure, in the form of radio waves. The control unit receives the signal through an antenna. Each transponder is coded and initialized to the vehicle at the factory.

If a tire’s pressure drops to approximately 26 psi, a warning light graphic on the dash illuminates to alert the driver to low pressure.

System capabilities vary depending on the Nissan vehicle. On some Nissans, the system features only the warning light. On others, the system also displays individual tire pressure readings as part of the trip computer readout, Vehicle Information System, or Advanced Drive-Assist Display.

Should I Patch or Plug a Tire that has a hole in it?

Here at Nissan of LaGrange we are often asked if we will patch or plug a tire for a customer that has a puncture. In the interest of our customer’s safety we have decided that it is much safer to replace the tire instead of a temporary option like patching or pluging a tire.

According the the  Tire Industry Association’s website

“A plug by itself or a patch by itself is not an acceptable repair because the plug does not permanently seal the innerliner and the patch does not fill the void left by the penetrating object, which allows water to enter the body of the tire and starting corroding the steel belts.”

So next time you have a hole in your tire do the safe thing and have it replaced, and when you need your tire replaced bring it to Nissan of LaGrange. We offer the tires that came on your Nissan (or any other manufacturer) from the factory at a great price. Plus, We may be able to offer some other tire options that may save you even more $$$. So, Drive safe and get that tire replaced.

4 Most Common Tire Wear Problems

Today’s Nissan cars, trucks, and SUVs are fitted with advanced safety systems. Yet the four small contact points of rubber on the road remain among the most important safety features — and are perhaps the easiest to overlook. Tires also affect vehicle performance, ride comfort, and fuel economy.

Tires should be checked for inflation pressure and tread wear periodically. A tire with incorrect pressure or worn tread has diminished road-holding capability and can be a hazard. Certain types of tread wear also can indicate serious vehicle problems that should be corrected immediately.

We asked our Nissan Factory Technicians what causes most tire wear issues. The following  are the four more common problems and their tread wear warning signals.

Over/Under Inflation

An over-inflated tire prevents the sidewalls from flexing, resulting in rapid wear at the center of the tread. An under-inflated tire allows the sidewalls to flex excessively, resulting in rapid wear at the edges of the tread. This issue is usually corrected by inflating the tires to the proper tire pressure. If you drive with the incorrect pressure too long you may need to replace the tires much earlier than you planned.

Excessive Toe-In or Toe-Out

Excessive toe-in or toe-out causes a tire to be dragged at a slight angle as it rolls forward. This will wear the entire tread to one side, as well as diminish performance and fuel economy. Excessive toe-in or toe-out is usually corrected by adjusting the steering or suspension system with an alignment

Excessive Camber

Excessive positive or negative camber will wear a tire’s tread more rapidly on one side or the other. Excessive camber is usually corrected by adjusting the suspension system with an alignment.

Unbalanced Wheels

When a wheel is not properly balanced, the driver will experience vibrations in the vehicle while driving. This occurs when the wheel and tire is heavier on one side than the other. As the wheel spins, the heavy side will cause it to bounce. In extreme cases the tire will actually lose contact with the pavement as it bounces up and down. Unbalanced wheels can usually be corrected by having them balanced and then road tested for driving comfort.
