How Thick Are Tires?

Generally, the tread thickness of car tires is around 13mm (7mm for tread pattern depth and 6mm for tread thickness), with the sidewall thickness being 5mm. Tire Classification: Automotive tires can be divided into pneumatic tires and solid tires based on their carcass structure. Most modern vehicles use pneumatic tires. Depending on the internal air pressure, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Classification of Pneumatic Tires: Low-pressure tires are widely used in various vehicles. Pneumatic tires can also be divided into tube tires and tubeless tires based on their construction. Tubeless tires are commonly used in passenger cars.
The thickness of tires, what I encounter most often is the tread depth. New tires are generally quite thick, around 8/32 of an inch, which is equivalent to 6 to 8 millimeters. After driving for a long time, wear and tear will make them thinner. I once drove in the rain when the tread was almost worn out, and the brakes slipped, which scared me into replacing the tires immediately. Now I use a simple method to check: insert a one-yuan coin into the tread groove. If you can still see the copper part, the thickness is acceptable; if it's completely exposed, it's time to replace them. Safety on highways depends entirely on them. If the tread is too thin, it's prone to blowouts or loss of control. I recommend checking the tread depth every quarter and keeping it above 3/32 of an inch for optimal safety.
