1 kwi 2021 · The idea of the penny test is to check whether you’ve hit the 2/32” threshold. Here’s how it works: Place a penny between the tread ribs on your tire. A “rib” refers to the raised portion of tread that spans the circumference of your tire. Tire tread is composed of several ribs.
7 sie 2022 · The minimum safe tread depth is legally considered 2/32″, however, 3/32″ or 4/32″ are significantly safer tread depths. You can replace tires earlier than 2/32″ to significantly improve traction in wet conditions.
20 wrz 2024 · Place a penny in between 2 ribs on your tire with Lincoln’s head pointing down into the tread. If only part of his head is covered, it means your tires are in good shape. If you see his entire head, your tread is 2/32” or deeper and it’s time for a tire replacement.
To check your tread, there are four quick and easy methods. First, grab a penny and insert it into your tire's tread groove with Lincoln's head upside down and facing you. If you can see all of Lincoln’s head, your tire tread depth is less than 2/32 of an inch, and it's time to replace your tires.
If your tires fail the penny test, it’s time to measure the tread depth across the entire tire using a tread depth gauge. The legal limit for tread depth varies by state, but is typically 2/32 of an inch.
The penny test is an accurate way to measure whether tire tread depth surpasses or falls short of 2/32nds of an inch, since 2/32nds of an inch is the universally standard distance between the top of Lincoln’s head and the edge of the coin (see above for an explanation of how to do the test).
19 wrz 2024 · To lower your risk for vehicular accidents associated with low tire tread, check your tire tread using the penny test, the quarter test, by examining the treadwear indicator bars molded into your tires, or using a tread depth gauge.
