What is the tread depth on a brand new tire?
If Lincoln's entire head is visible, the tire is worn to approximately 2/32" and is considered legally worn out in most States. Average new tires used on cars typically start with 10/32" to 11/32" of original tread depth.
The Penny Test. In the United States, tire tread depth is measured in 32nds of an inch. New tires typically come with 10/32” or 11/32” tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models.
- Tire Width. Is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P215/65 R15 tire, the width is 215 millimeters.
- Alignment refers to an adjustment of a vehicle's suspension – the system that connects a vehicle to its wheels. It is not an adjustment of the tires or wheels themselves. The key to proper alignment is adjusting the angles of the tires which affects how they make contact with the road.
- In the United States, tread depth is measured in 32nds of an inch. As mentioned above, tires are legally "worn out" In most States when they reach 2/32" of remaining tread depth. For example, a typical tire that starts with 10/32" of original tread depth has only 8/32" of useable tread depth.
Simply insert a penny into your tire's tread groove with Lincoln's head upside down and facing you. If you can see all of Lincoln's head, your tread depth is less than 2/32 inch and it's time to replace your tires.
- Do not slam on the brakes. Take your foot off the accelerator and gently apply the brakes. Steer straight ahead to a stop. When you are able to do so safely, pull the vehicle off the road.
- However, check your owner's manual to see if there is a recommended rotation scheme. During rotation, each tire and wheel is removed from your vehicle and moved to a different position to ensure that all tires wear evenly and last longer. Tires should be rotated every six months or 6,000 to 8,000 miles.
- "The tires are designed nowadays to do 50-60,000 miles. But when they get down to those wear bars, you don't have as much tread," Allen said. "And I recommend right when it gets down to those bars, you replace your tires." Other factors that you should be on the lookout for are weather cracking and sidewall integrity.
