Should I replace tires before wear bar?

When the tread has worn down to the level of the wear bars, it’s time to replace your tires. This means you’ve reached the legal tire tread depth limit, and your tires are no longer safe to use. Most manufacturers may suggest replacing tires sooner to help keep you safer on the road.

How much tread is left at the wear bar?

Passenger vehicle tires are marked with minimum tread depth indicators called “wear bars,” which are structured into the major tire grooves. When the wear bar is even with the surrounding tread, then that’s an indication that 2/32-inch of tread depth has been reached, and the tire is no longer serviceable.

Why does it sound like something is hitting my tire?

There are quite a few parts that can fail and cause this, but there are two common caused of this. The most common being a bad tie rod end. It can be the outer tie rod end at the wheel or the inner tie rod end in the rack and pinion. Both of these are common failures.

Do tire wear indicators make noise?

Abnormal Tire Noise Abnormal tire wear, such as feathering or cupping, can be caused by alignment or suspension problems. Once the tread surface is no longer smooth, the tires will generate more noise. Tire replacement is necessary, but suspension repair and realignment will prevent the problem from resurfacing.

How can I tell if my tire tread is worn?

Some small tires (12-inch rim or smaller) only require a minimum of three tread wear indicators. Each tire wear indicator on a tire provides a visual indication of whether the tread is worn to 2/32″. When you visually inspect one of your tires, find a tire wear bar and see if it is flush with the rest of the tire’s tread.

Is it normal for tires to be noisy?

Yes, when you get near the wear indicators most tires becomes quite noisy. This is common. What you likely have is irregular wear, which is caused by misalignment and aggravated by insufficient inflation pressure and insufficient rotation practices.

How can you tell if a tire has reached its limit?

There are several ways in which you can determine if your tire’s tread depth has already reached its limit. Modern tires already come with wear bars. These are tire tread depth indicators that are present within the grooves of the tire. Brand new tires will have these wear bars deeper into the groove.
