FIXD makes it easy to track the life of your tires over time. In the Maintenance section of the app, click the Tires icon at the bottom of the screen. Update your vehicle’s mileage. A representation of your car appears, with the date of your last measurement (if any) below each tire. Measure the tread depth of that tire on your vehicle using a penny. Then click on that tire in the app, and swipe up on the screen until the green area covers as much of the penny image as your tread covers on your actual penny. Click Save. Repeat this process for the other tires, and this information is now recorded in FIXD. As you continue measuring your tread depth over time, you’ll be able to see how long it takes your tires to wear over time. This will help you plan ahead and set money aside for new tires by the time you need them. For example, if it takes two years for your tread to go from 10/32” to 6/32”, you can estimate that you’ll need to replace your tires in another two years when the tread depth reaches 2/32”.
