The tread on your tires is critical when it comes to maintaining your vehicle’s safety and performance. Tires become less effective as their tread wears away, so it’s important to make sure it doesn’t get too low. Tread depth measures the amount of rubber on the tire from the top to the bottom of its deepest grooves. Most new cars have about 8mm of tread depth, and tires should be replaced once they get down to 3mm. Driving on tires with less than 3mm tread depth puts you at serious risk on the road. Tire tread is especially important for driving on wet roads, but it’s important for driving on all types of surfaces. To measure your vehicle’s tire tread depth, you’ll need a tread depth gauge, or you can utilize your tire’s built-in tread indicators. Push the gauge into the tire’s shallowest groove and push the shoulders flat against the tread before checking the result.
