Depends on the state you live in. Canada and 42 states require at least 2/32". Two states list 1/32" as the minimum and 6 states have no minimum at all. In my opinion based on years of experience you should replace your tires when they have 3/32" of tread left for the safety of you and your family.

Slow down and make sure your tires have at least 2/32" of tread depth.
Minimum tread depth for all 4 tires is 2/32"
When the tread (the pattern in the tyre) is wearing thin. In Britain the law says the tread must have a depth of at least 2mm. Other countries may have different legislation.
When your tires have 2/32" tread depth left you need to replace them.
In Oregon there is no minimum thread depth, but just that Oregon requires that tires be in safe operating condition, without any bulges or exposed cords.
That depends on who old/used the type is.
I inspect the tire and measure the tread depth.
2/32
1/32
In the United States, the tread has to be 4/32 (3.17mm) or more on the front tires and 2/32 (1.58mm) or more on the back tires. rear tires can be retreaded but not the front "steer" tires.
Loss of traction poor tread depth on tires
You get a credit towards the purchase of new tires based on the tread depth of your existing tires. The larger the depth the bigger the credit. anonymous@oola.com
