Tire Pressure Safety

Frequently Asked Questions

What is direct TPMS?

Direct TPMS employ pressure sensors on each tire. The sensors physically measure the tire pressure and temperature in each tire and report it to the vehicle's monitor.

Do you have an owner's manual?

We sure do. You may download it here.

What vehicle types does the TP2 cover?

We cover all passenger vehicles including light duty vehicles under 10,000 lbs gross volume weight, and including certain trucks, rv's, buses and trailers.

How does tire pressure affect my safety?

The National Highway Traffic Safety Administration (NHTSA) has estimated that 1660 U.S. automobile accident fatalities annually are caused by underinflated tires.

What exactly does it mean when my TPMS warning light comes on?

If the TPMS warning light comes ON and stays ON, take caution. This means that one or more of your tires may have a low-pressure condition. You should carefully slow the vehicle and park in a safe and secure place. You should then inspect all of your tires and check the air pressure.

Why does tire pressure change?

Many factors affect tire pressure including ambient temperature changes and tire damage such as punctures. Tire pressure drops about 1 psi for every 10°F drop in ambient temperature. Additionally, tires can lose as much as 1.5 psi per month as air escapes the tire and rim naturally.

What should my tires be inflated to and where can I find that?

Tires should be inflated to the vehicle manufacturer's recommendation as found on the vehicle tire information door placard. The vehicle placard is normally located on the inside door panel or door itself. In many cases the specified tire pressure can also be found in the vehicle owner's manual. The pressure indicated on the sidewall of the tire should not be your guide, as that is the maximum inflation pressure for the tire itself, not for the tire when used on your specific vehicle.

What do I do when my TPMS light comes on during cold weather?

Any time that the TPMS warning light comes ON, there is a possible low tire pressure condition. Tire pressure can drop due to cold conditions, and this drop in pressure may cause the TPMS light to come ON. As the tire warms up under normal driving conditions, the light may turn OFF. If the cold weather conditions cause the TPMS light to stay ON, check the tire pressure (when tires are cold) and inflate the tire to the proper pressure indicated on the door placard.

Can having TPMS in my car really save me money?

Yes, properly inflated tires save money at the pump due to better fuel efficiency. According to FuelEconomy.gov, a joint Web site of the U.S. Department of Energy (DOE) and the Environmental Protection Agency (EPA), underinflated tires can lower gas mileage by 0.3% for every 1 psi drop in all four tires.

What if I have an extra set of tires and wheels (for snow tires or custom wheels)?

You can purchase a set of replacement sensors and have them installed in your extra set of tires or wheel assemblies. When the extra set of tires or wheel assemblies is mounted to the vehicle, your TPMS installer will have the ability to relearn the new sensors to the vehicle computer.

What if I have a roadside flat and try to plug the hole using off-the-shelf tire sealant?

Any time that a substance other than tire service center air or nitrogen is introduced into the tire, there is the potential to damage the TPMS sensor in the tire. However, if tire sealant has been used, your local TPMS installer can assess the sensor functionality and determine if the sensor is working properly or if it needs to be repaired or replaced.
