Autos: tire wear bars

Self-tutoring about tires: the tutor continues about them.

Yesterday, wondering if the summer tires would be good for another season, I discovered “tire wear bars” on the internet.

Tire wear bars, apparently, run across the tire, in the grooves. The tires I checked had two sets of them. They start out deep below the tread pattern: on a new tire, the tread pattern is about 5/16″ deep. The wear bars are about 1/16″ deep.

If the tread is worn to the point that it’s level with the wear bars, the tire obviously needs to be replaced, and it’s potentially illegal to drive on. If, on the other hand, the wear bars are clearly below the tread pattern, the tire, based on tread depth, is still good.

I’d never known of tire wear bars before, but easily found them while examining the tires.
