Hand Holding Tire Gauge to Tire

Knowing how to properly inflate your tires will help you extend the life of your tires. As an added bonus you will also improve ride quality, fuel economy, and overall handling. If you want to know how to fill your tires with air, the service team at INFINITI of Chattanooga is happy to share some insight. Reading on you will find information on why it is important to know the recommended psi (Pounds per Square Inch) for your INFINITI tires, and how much air you should add to your tires.

Adding Air to Tires: Step-by-Step Guide

Even if you’ve never adjusted your car’s tire pressure on your own, you will quickly find that this can be an easy task. To add air to your tires, follow these steps below: 


  • Pull up to the air dispenser at your local gas station. 
  • Make sure you can reach all four tires with the air hose.
  • Remove the cap from the tire valve on the first tire.
  • Then, use your tire gauge to check the air pressure in the tire.
  • Repeat this process for the other three tires. 


How to Reliably Measure Tire Pressure

Sometimes, the air hose gauges at gas stations are not 100% reliable. It is a good practice to have your own tire pressure gauge stored in your vehicle for this reason. You will want to avoid overinflating the tire. Use the air hose to add air in short bursts and make sure that regardless of what the second reading is you only top up what was lost before visiting the dispenser. Most vehicles have a recommended tire pressure range listed in the owner’s manual. Many tires will even have it listed on their sidewall.


How to Fix Overinflated Tires

If the tires are overinflated, it is an easy matter to correct. You just release some of the air. This can be accomplished by pressing the pin on the tire valve with the back of the air hose nozzle or use the small knob on the back of the rounded end of a tire gauge. Occasionally we all encounter situations where we need to adjust the pressure more than once. 

How Much Air Should I Put in My Tires? 


You will find the recommended tire pressure for your INFINITI vehicles shown on a sticker inside the driver’s door. If you do not find the sticker, you can check the owner’s manual; there, you’ll find everything you need to know about your car’s tire pressure. Passenger cars generally suggest 32 to 35 psi (pound per square inch) when they’re cold. To get the most accurate reading, check the tire pressure after the car has cooled off. While inflating your tires, keep the following information in mind: 


  • The psi given on the actual tire is the maximum for the tire, not its recommended psi.  
  • If the ride quality is bouncy and the car is harder to handle, your tires may be overinflated.
  • When tires are underinflated your vehicle’s fuel economy may have a slight decline and the tires will wear out quicker.
