A simple way to check tread is the penny test: Stick a penny into the tread grooves with Lincoln’s head upside down. If you can see the top of his head, it’s time for new tires. This quick check helps ensure good grip on the road, especially in rain and snow.
Checking your tire tread depth at home is an easy habit that keeps you safe on the road by ensuring your tires have enough grip, especially in wet or slippery conditions. Good tread helps channel away water and debris, reducing the risk of skids or hydroplaning. It’s something anyone can do without fancy tools and making it a monthly routine can prevent surprises.
One popular method is the penny test: Take a penny and insert it into the tread groove with Lincoln’s head upside down and facing you. If you can see the top of his head, your tread is very low (at or below 2/32 of an inch) and it’s time for new tires. For a bit more precision, use a quarter: Insert it with Washington’s head down; if the top of his head shows, you’re at about 4/32 inch, which is okay but worth watching, especially for winter driving where deeper tread is better.
You can also buy a cheap tread depth gauge from any auto parts store for exact measurements. Check multiple spots on each tire, including the center and edges, since wear isn’t always even. If numbers vary, it might signal alignment or pressure issues.
Remember, legal minimums (in most states) are 2/32 inch, but experts recommend replacing them at 4/32 or higher for better performance. Low tread means longer stopping distances and less control.
