In the US, there’s a simple trick to checking your tire tread to see if you need to replace it. It’s called the Penny Test, and it can help determine how much your trailer tires have been worn down.
You can try the Penny Test in three simple steps:
Step 1: Find a penny.
Step 2: Turn Lincoln’s head upside down.
Step 3: Insert into tire tread rib.
If the top of Lincoln’s head disappears into the tread, your tread is still deep enough. If all of his head is visible, you should look into purchasing new tires.
If you have any doubts about your tires, you should get them checked by a professional. Do-it-yourself tricks like this are handy for day-to-day maintenance, but nothing beats the eye of someone who knows what they’re doing. Here are some of our best tips to avoiding tire wear and tear.
