    dang, trucks have terrible braking performance!

    It looks like we need to see tests of 6/32" and 8/32" tread.

    Another thing to consider by the time you get down to 4/32 the rubber probably has hardened over time so performamce with be even worse.

    Did the drivers in the test know which tires they were using?

    By the way in Ontario, Canada they changed the regulations so that tires need 2mm of tread to pass a safety test which is about 2.5/32

    In southern California or wherever the road is dry all the time, bald tire actually performs better!  It got more surface area.  Don't waste your money!

    No. It's not a good video. It's actually very misleading. Stopping distance on the 10/32" = 195.2ft, stopping distance on the 2/32" = 378.8ft. 378.8/195.2 = 1.94. That means stopping distance is increased by 94%, or almost doubles with the 2/32" thread. Bad? Yes. But, the video is NOT to scale. The car in the 2/32" scenario should have not left the screen. The author is trying to make us panic. 94% extra means the car should stop just short of the half way mark on the screen.

    Speaking from real world experience, I got a feeling that my tires would not hold on to the road well when it rained heavily, I had around 4/32" left. My tires felt like they weren't gripping the road so I was going at 65mph. But it wasn't until when I tried braking during downhill when I realized I needed new tires. Tapping on my breaks lightly the car would just go down. I slammed on the brakes and my ABS came on like crazy. I think 4/32" is a good time to change your tire…

    Yes, the stopping distance is effectively doubled when the tire is worn down to 2/32” remaining depth. But our testing revealed the impact of shallower tread is non-linear. Wet stopping distance gets longer as the tire wears, but as the tire wears below 4/32” remaining the wet performance really begins to fall off much more rapidly. That’s why we recommend replacing tires at 4/32” if you have to drive in wet conditions.

    Would be great to see this with new/worn on front/rear to quantify that effect as well.

    @LtBullitt351 LOL! This coming from the guy that said "I'm a danger to society."

    @LtBullitt351 Then you can't afford to safely drive. Why risk your life and others?

    Great video… Gives good side by side comparison and also shows how to read the tire depth guage which I could not find in other videos.

    Incredible! I have been agonizing over replacing the 4/32 pair of rear tires on my truck for weeks now, but been trying to find out if I really NEEDED to, before dropping $260.00 for a pair of new ones! This answered my question perfectly! I know now it will be perfectly safe to wait a few more weeks till I get income tax money, rather than break the bank now!

    There is a mathematical formula that determines how much breaking force can that can be applied to a particular vehicle. For some front wheel drive vehicles with almost twice as much weight on the front than the rear ,newer tires on the rear will decreases stopping distance by 25 percent..

    Great video, excellent.

    This video is fantastic! Great visual measurements for the consumer to make a informed decision on when to change their tires.
