Why Tire Tread Depth is Very Important For Safe Driving
Without the proper tread depth, your chances of getting into an accident also increase. The main purpose of tire tread is to keep water churning out from under the tire during inclement weather. Without it, the water gets trapped under it, making it very slippery. In fact, a study conducted by Smithers Rapa in 2013 found that tread depth at 2/32 going at 60 mph requires about a 10-car space stop compared with the 10/32, which can stop very quickly. SAE International found that the chances of accidents increase significantly with tread depths of 4/32.
If you believe that your tires are getting low, it is important to take measurements and take action accordingly. Tire tread depth is measured in 32nd’s of an inch. Ideally, your tread depth should be about 10/32 of an inch, deeper if you live in an all-terrain area or when winter’s about to kick in. If it’s between 4/32 and 5/32 of an inch, then you have a very high chance of hydroplaning on wet cement during inclement weather. If it’s less than 3/32 of an inch, you need to get your tires either replaced or aired without delay. It is also illegal to drive on.
Fortunately, there are several ways to measure the tread. If you insert a quarter into the tread and you can see the top of Washington’s head, that means that your tire is at 4/32. The same case with Lincoln’s head on the penny head-down means that it’s at 2/32 of an inch. A depth gauge can be put on the tread to get the exact measurement of it. You can also check whether the tread is at the same level of the tread-bar by checking the tread-wear bar just above the arrow.
