The legal minimum safe tire tread depth is 2/32 inches and tires should have a wear indicator which becomes visible when the tires are worn down enough to need replacement.

Any tire tread depth above 4/32 tire tread depth is considered good and anything below that tread depth is considered wearing out to where it's becoming unsafe.

If your tire tread depth gets below 4/32 then it's usually time to replace them.

Driving with low tire tread is okay as long as the tire tread is not too low.

The tire tread is responsible to help your car gain traction on the road and helps your vehicle stop safely when you step on the brakes.

Driving on low tire tread especially during icy and wet road conditions can be unsafe and cause you to get into a car accident.

If you stick a penny in the tire tread and the penny shows the top of Lincolns head then the tires should be replaced.

When tire tread gets low you lose the traction from your tires so it can be hard to stop faster and you might slide on wet pavement.

The tire tread on the tires is what helps the tires grip the road and also helps you stop.

Without proper tire tread your car or other vehicle would be harder to stop so if your tire tread is wearing down you should replace the tires.

If you stick a penny in the tires tread and see the top of Lincolns head on the penny then the tire tread is worn down enough to need replacing.

Also if the tires are 10 years old or older you should replace the tires with new ones regardless of tread depth because the rubber cracks and the steel belts separate in the tire which can lead to a blowout.

Most tires last around 50,000 miles before needing replaced due to tread depth however if the tire is 10 years old or older it should be replaced regardless of tread depth.
