What do tire wear bars indicate?
Designed specifically to help you gauge your tire health, indicator bars are small tread marks that are cut off at the lowest safety point in your tire tread. These bars are often raised to 2/32”, the hazard point in most tires. When your tread aligns with the wear bars, it means you are ready for a new set of tires.
What depth are wear bars on tires?
2/32″
Tire wear bars sit at 2/32″ of tread depth, which is the lowest tread depth allowed by the law – this depends on state to state, but most in most states you can drive your vehicle with that much tread left. Tread wear indicator bars help you visually measure the tread depth left on your tires.
Are there wear bars on tires?
Tread wear indicators, or wear bars, are spaced evenly through the main grooves in the tire tread. If they are flush with the level of the tread, then the tire should be replaced. Several winter tire models are equipped with winter tire wear indicators.
What depth are tread wear indicators?
1.6 mm
On the side of the tyre are the letters TWI (Tread Wear Indicator). When the tyre’s tread depth is down to 1.6 mm (1/16 inch), the tread will be level in height with the tread wear indicators. Change to new tyres as soon as possible.
Do tire wear bars make noise?
Excessively Worn Tires If you’ve ever driven a set of tires all the way down to the 2/32” minimum, with the wear bars showing through the tread, you’ve probably noticed a harsher ride as well as poor braking and handling and more noise. That’s because there’s simply less rubber to soak up and suppress sound waves.
What do tread wear bars look like?
Tread wear indicator bars are small, raised bars found within the grooves of your tires between the tread markings. They are placed all around the tire at different points to measure how evenly your tread is being worn down.
How much tread is on a new Bridgestone tyre?
around 8mm
New tyres are manufactured with around 8mm of tread depth, but this wears away over time, which compromises the car’s road handling, ability to cope in wet conditions, road grip and safety.
How do I know when my Bridgestone tire expires?
DOT Number It’s easy to identify – look for the letters “DOT” followed by eleven or twelve letters and numbers. On tires made after the year 2000 the final four digits signify the week and year of manufacture. So, a tire with “3618” would have been made in the 36th week or 2018.
Do tires get noisier as they wear?
Tires get noisier as they wear because of their construction, tread design and uneven wear. As a tire wears and the thickness of the tread and its sound insulating properties are reduced, it gets closer to its belts and reinforcements – this can increase tire noise.
Why are my new tires so noisy?
New tires may produce a different (or more) noise than the previous tires due to different tread patterns and tire compounds. Brand-new tires also may need a few miles to “break in.” The wider the tire, the larger the tire’s contact patch on the road, which can increase the road noise.

How many tread wear bars do I need on a tire?
Most tires have at least six or more tread wear bars. 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″.
