How to check your tire tread depth at home 

How do I use a penny or ruler to check my vehicle’s tires? 

The tread on your tires is crucial in maintaining traction and ensuring your safety on the road. Over time, your tire tread will wear down, and it’s essential to keep an eye on its condition. Checking your tire tread depth regularly can help you catch issues early and prevent accidents. Visit Matt Castrucci Kia for new tires in Dayton, OH. 



A step-by-step guide to assessing your tire’s wear 

Checking your tire tread depth is a simple task that can help keep you safe on the road. By following these steps and performing regular checks, you can catch issues early and ensure your tires are in good condition. Don’t forget to replace your tires when they reach the minimum recommended tread depth, and always prioritize safety when driving. 

Step 1: Gather Your Supplies

To check your tire tread depth, you’ll need a few supplies: a penny, a ruler or depth gauge, and a flashlight (optional). Make sure your car is on a level surface and that the tires are cold (i.e., you haven’t driven the car in at least an hour). 

Step 2: Locate the Tread Wear

Indicators Most tires have tread wear indicators in the grooves of the tire. These are small bars that run perpendicular to the tire’s tread. If the bars are level with the tire’s tread, it’s time to replace the tire. If you don’t see these bars, don’t worry; you can use the penny test to check your tire tread depth. 

Step 3: Perform the Penny Test  

Take a penny and insert it into the groove of your tire with Lincoln’s head facing down. If you can see the top of Lincoln’s head, it’s time to replace your tires. If Lincoln’s head is covered, your tires still have adequate tread depth. 

Step 4: Measure the Tread Depth

If you want to accurately measure your tire’s tread depth, use a ruler or depth gauge. Place the gauge in the groove of the tire and measure the depth of the tread. The minimum recommended tread depth is 2/32 of an inch. If your tires have less than this amount of tread, it’s time to replace them. 

Step 5: Repeat for all Four Tires

 Remember to check the tread depth on all four tires, as they may wear at different rates. If you notice that one tire has significantly less tread than the others, it may be time for a rotation or alignment.
