Tire Tread Depth Chart - How to Measure and When to Change Tires

When we are busy, we tend to be more focused on where we are heading instead of the means of getting there. No wonder that we get concerned about how much energy is left in our car’s tires at one point. The best way to tell whether the tires are about to retire or are safe for another season is by checking the tread depth.

Tires without enough tread depth are always at greater risk of punctures, hydroplaning as well as reduced traction. By measuring tread depth regularly is a simple way to make sure that your tires can perform safely.

How do we check the tire tread depth?

Tread depth can be checked in the following three ways.

• Checking tread depth with a quarter

In this method, you have to slip a quarter between the tread blocks. By having the caribou’s nose facing you and the tread covers it, then it is a sign that the tires are left with adequate tread. If the nose of the caribou can be seen by you, this indicates that the tires are worn and must be replaced immediately.

• Checking tread depth with indicators or tire tread wear bars

These days, we can see several tire brands that come with built-in tread wear indicators. Normally, these are six raised bars that are molded in the grooves of the tread to show the tread depth that is allowed. If you find these indicators to be worn, then you will certainly have to replace the tires.

• Checking tread depth with a tread depth gauge

One of the best and easy ways to determine whether your tires are good for use or have to be replaced is using a tire tread depth gauge. You will find the tire tread depth gauge at the majority of the gas stations, and various drivers keep the indicator in their glove compartment so that they can access it easily.

What do the gauge measurement readings mean?

• When you have 6/32”, it means that the tread depth is fine for at least the next three seasons.
• When the tread depth is 5/32" and you have to drive on the wet roads most of the time, then you need to consider replacing the tires.
• 4/32" – 3/32" indicates that you must replace the tires much sooner, but keep in mind that 4/32" is a minimum in case of a winter tire.
• 2/32” tread depth shows that your tires have to be replaced as they are legally bald.

Bottom Line

Your tires can offer a reduced risk of punctures, better traction, and a greater ability to push the water away to get rid of hydroplaning on the wet roads when the tires are on or above the tread depth level that is recommended. When checking the tread depth on the tires, check the tire pressure and search for any unusual wear signs of aging and damage, including abrasions, bulges, and cracks.
