1/8 th inch, a little more if you encounter wet roads to help prevent hydroplaining..
It is the depth of the grooves in the tyre.
The four main characteristics of a tire tread are tread pattern, tread depth, tread compound, and wear indicators. The tread pattern affects traction and handling performance, while tread depth impacts grip and water displacement. Tread compound refers to the rubber's formulation, influencing durability and performance in various conditions. Wear indicators help monitor tread wear, ensuring safe performance as the tire ages.
If you mean tire tread depth, the minimum is 1.6mm.
You should measure tire tread depth in several locations across the tire to get an accurate assessment of wear. The best places are the grooves in the tire tread, specifically in the center, on the inside, and on the outside edges. Use a tread depth gauge or a penny to check; placing the penny with Lincoln's head down into the groove will help you determine if the tread is deep enough. Generally, a tread depth of 2/32 of an inch or less indicates that the tire needs to be replaced.
That depth present on a new tyre.
Minimum LEGAL tire tread depth is 2/32nds of an inch.
The minimum tyre tread depth in the UK is 1.6mm.
The average tread depth of a new radial tire is typically around 10/32 to 11/32 of an inch. This tread depth provides good traction and performance while allowing for gradual wear over the lifespan of the tire.
All tires on vehicles driven in Missouri must be safe. There is no listed minimum tiretread depth or mention of tire grooving in the laws.
A tire is considered illegal if the tread depth is less than the minimum requirement set by law, which varies by region but is often around 2/32 of an inch (1.6 mm) in many areas. Insufficient tread can significantly reduce traction, especially in wet or slippery conditions, increasing the risk of accidents. Regularly checking tire tread depth is essential for safety and compliance with legal standards. If the tread is worn down to this limit or below, the tire should be replaced immediately.
UK is 1mm
In California, the minimum legal tire tread depth is 1/32 of an inch for passenger vehicles. However, it is recommended to replace tires when tread depth reaches 4/32 of an inch for better wet traction and safety. Regularly checking tire tread can help ensure optimal performance and reduce the risk of hydroplaning.
