Proper and adequate tread on vehicle tires can help a person by keeping his car on the road,steering correctly and able to stop quickly if needed.

When the tire tread wears down to the wear bars, the tires are ready for replacement.
Look on the side of the tire and you will see a set of number such as 195/50 17R. The first number, in this case 195, is the tread width in millimeters.
Sounds like an old tire size from before the current numbering system. 7.5 inch wide tread on a 15 inch rim.
The humming noise is dependant on the road surface/ tire tread and tire wear. If the tires are scalloped or feathered they will hum. Vibration may be a problem in your suspension or the balancing of one or more of your tires. You can run your hand over the tread (front to back and back to front) if it is wavy or the tread feels jagged/ sharper in 1 direction, you need suspension work and/or an alignment.
yes. but the biggest preventatives are proper tire pressure and alignment angles (toe, camber)
The three important tire checks to make are proper inflation(pressure), adequate tread(tread depth), and normal wear(wear and tear).
Tread life refers to the longevity and durability of a tire's tread, indicating how long it can maintain optimal performance before it wears down. It is typically measured in miles and can be influenced by factors such as driving habits, road conditions, and tire maintenance. A longer tread life signifies that a tire can provide better traction and safety over an extended period, making it a crucial consideration for consumers when selecting tires. Proper care, such as regular rotations and maintaining correct tire pressure, can help maximize tread life.
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.
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.
It is an indicator of tire tread wear.
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.
Tire treads can actually increase friction by providing better grip on the road surface. The design and depth of the treads help to channel away water, snow, and debris, maintaining contact between the tire and the road for improved traction and control. Proper tread patterns are important for ensuring adequate friction levels in various weather conditions.
If you mean tire tread depth, the minimum is 1.6mm.
Minimum LEGAL tire tread depth is 2/32nds of an inch.
Tire spec in PA is 2/32 of an inch of minimum tread
1 mm on whole tire. If any part of tread is less then it should be replaced.
