Tire Tech: Measuring Tire Tread Depth with a Coin. U.S. coins can be substituted for a tire tread depth gauge as tires wear to the critical final few 32nds of an inch of their remaining tread depth. Place a penny into several tread grooves across the tire. If part of Lincoln's head is always covered by the tread, you have more than 2/32" of tread depth remaining.
How to Measure the Tread Depth of Your Tires. There are basically three ways to measure tread depth: the quick-and-dirty way, the quicker-and-dirtier way, and the right way. All three will tell you if your tires need to be trashed for new ones, but only the right way will tell you anything else.
If any of the tread grooves are below minimum tread, then it’s advisable to replace. Sufficient tread depth in one area of the tire doesn’t compensate or cover for insufficient tread depth elsewhere on the tire. If the top of the Lincoln Memorial is covered, then you have more than 2/32" of tread.
Fortunately, measuring tread depth regularly is a simple and surefire way to help ensure your tires will stick to the road and keep you safe. Slip a toonie in between your tread blocks. If the tread reaches the bear’s paws, your tires have lots of tread left (they’re probably new!).
How To Measure Tire Tread. Tire tread is really important for maintaining traction on the road, preventing blowouts, and avoiding hydroplaning. The US Department of Transportation says you should replace your tires if the tread wears down to less than two 32nds of an inch (2/32”). If you’re driving in an area that has a lot of rainfall and wet roads,...
Tire Tech Information - Measuring Tire Tread Depth with a Tire Gauge …to estimate remaining tread depth as a tire approaches the end of its useful life, the established method of measuring remaining tread depth in the U.S. is with a gauge that reads in 32nds of an inch (other countries measure tread depth in millimeters).
Tire tread is typically measured in 32nds of an inch with a new tire coming in with about 10/32nds of an inch. If fractions really are not your thing, you can picture 10/32nds of an inch at about 1/3 of an inch.
Choose a point in your tire tread that appears to be low. Insert the penny into the grooves on the thread with Lincoln’s head pointed down. 4. Look at the penny. If any part of Lincoln’s head is obscured by the tire tread, your tires are fine. Otherwise, your treads are too shallow and you should replace them.
Tread Depth Gauge. A simple way to check your tire tread depth is by using a tread depth gauge. You can find tire tread depth gauges at your local auto parts store. There are many models available, but an inexpensive simple graduated probe gauge will work just fine.
Tread Depth Gauge. Carefully evaluate your tire to find the lowest, most worn area along the tire’s tread, and place the probe end of your tread gauge into the void between the tread blocks. Gently push down on the gauge’s handles until the handles meet the top of the tread blocks and stops. This will cause a bar to extend out from the opposite end,...
