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).
It is an indicator of tire tread wear.
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.
The tread is what grips the road.
To maintain and improve the durability of bike tire tread, regularly check tire pressure, avoid riding on rough surfaces, rotate tires periodically, and keep tires clean and properly inflated. Additionally, using tire liners or puncture-resistant tires can help prevent flats and extend the lifespan of the tread.

The outside of a tire consists of the tread and sidewalls.
