Pumping Air

Your vehicle’s Tire Pressure Monitoring System (TPMS) continuously monitors the air pressure in your tires.

When there is an instance of low tire pressure, or if the tire pressure drops below the manufacturer’s recommended level of tire pressure, the TPMS will detect and report the discrepancy by illuminating an indicator light on the dashboard of your vehicle.

When the TPMS light flashes on the dashboard, you should check your tire pressure, inflate the affected tire to the level indicated by the manufacturer, or bring your vehicle into one of our three locations so that the issue can be remedied by our expert staff.

During a TPMS maintenance service, our service staff will run a series of tests to ensure that the system is operating both correctly and at maximum efficiency.

If our technicians uncover damage to the system or its accompanying components, they may need to replace valve cores, valve nuts, seals, seal washers, or valve caps.

If you are in need of TPMS repairs, maintenance, or replacement services, or if you are in need of a TPMS installation service, then contact us today.

What is the Tire Pressure Monitoring System (TPMS)?

Tires operating below inflation standards put the overall performance of your vehicle and the safety of your passengers at risk. The Tire Pressure Monitoring System helps increase your safety on the road by improving your vehicle’s maneuverability, decreasing the tread wear of your tires, reducing your vehicle’s braking distance, and improving your vehicle’s fuel economy.

There are two types of Tire Pressure Monitoring Systems in existence today—Direct and Indirect. A Direct Tire Pressure Monitoring System uses sensors on the inside tire assembly to transmit tire pressure information to your vehicle’s computer.

An Indirect Tire Pressure Monitoring System gauges tire pressure through your vehicle’s Anti-lock Braking System (ABS) by using speed sensors to measure the rotational speed of each wheel (as tire pressure decreases, the rolling distance decreases, and the rotational speed increases).

All TPMS systems require regular maintenance in order to meet maximum performance standards, which requires all vehicles to be equipped with a Tire Pressure Monitoring System.

Pumping Air

The changing seasons and elevation will affect your tire pressure. But, if you suspect a slow air leak in your tire you should come into any of Sierra Car Care and MST Tire Centers 4 Full Service Vehicle Repair and Tire Stations to have your tire inspected. You may have debris, like, a nail in your tire, that should be repaired before causing further damage.

Air filled tires
If your tires are filled with air, then your tire pressure deflating is a seasonal event. Seasonal changes and altitude changes create a rise or drop in air pressure (for every 10 degrees change in temperature, tire air pressure changes 1 psi).

The concept is known as the ideal gas law.  PV equals nRT.  The “P” is pressure.  The “T” is temperature.  If the “V” (volume) the “n” (amount of gas, in “moles”) and the “R” (the “ideal gas constant,” which is sort of like pi) remain the same, a drop in temperature necessarily results in a drop in pressure.

The Benefits of Correct Air Pressure
Experts agree that keeping the correct air pressure in your tires is as important for your vehicle as an engine tune-up. In fact, the economic benefits may be greater as well. With the right amount of air pressure, your tires will:

  • Wear Longer
  • Save Fuel
  • Enhance Handling
  • Prevent Accidents

Failure to maintain the correct air pressure can result in poor gas mileage, reduce tire life, affect vehicle handling, and cause vehicle overloading. If you consider these factors, a routine tire pressure check would benefit the life of your tires and wheel components.

What are the benefits of Nitrogen filled tires?
Nitrogen is a beneficial alternative to air in tires. Rubber expands when heated, allowing tiny air molecules to escape, which may eventually lead to low tire pressure. Oxygen oxidizes when it reacts with other gases, like hydrogen. This means if hydrogen sneaks into your air-filled tire, water will form, and even the smallest droplets of water can lead to wheel corrosion and rust.

Nitrogen is a gas that does not support moisture, which means your wheels may experience less corrosion if you choose to fill your tires with nitrogen.

Sierra Car Care and MST Tire Centers 4 Full Service locations in the Reno area can offer nitrogen for you tires > Nitrogen Tire Inflation.
