Tire Tread Depth


How important is tire tread depth? Well, lets dive into that question. Tires typically start off with 10/32 inch to 12/32 inch of tread depth and are officially worn out at 2/32 inch. I have always preached that tires loose there ability to stop in the rain as they where designed to at 5/32 inch and new compelling research confirms this. AAA just came out with a study where they tested tires at a tread depth of 4/32 inch in the rain the results where astonishing. First 4/32 inch tires in the rain took up to 87 feet longer to stop and also degraded the drivers ability to control the vehicle by 33%. Second 4/32 tires stoping in the rain at 60 MPH verses new tires 10/32 inch stoping in the rain 60 MPH the results say it all. The vehicle with the worn tires was still traveling at a speed of 40 MPH when the vehicle with the new tires had already stoped. According to the NHTSA 9% of vehicle crashes are due to tire related issues. Just some food for thought.

You could also do the quarter test where you put a quarter in your tread with Washington’s head upside down if you can see the top of his head you have less than 4/32 inch tread and need to start looking for tires if you want to be able to stop in the rain as if your tires where new.
