What is the Difference Between Stock Tires and New Tires?

[McKevin]

The tread rubber and carcass rubber can be visually distinguished by their aging levels (uneven aging). The connection between the tire tread rubber and the sidewall may appear unnatural, with noticeable inconsistencies such as fractures, uneven rubber color, and varying rubber quality. The brand and tread pattern code marked on the sidewall may not match the actual tread pattern. Functions of tires: 1. Tires serve as the medium for transmitting forces between the vehicle and the road: They transfer driving force, braking force, steering force, etc., enabling the vehicle's driving, braking, and steering operations. 2. Supporting vehicle load: The vehicle's load causes the tire to compress until the average pressure on the contact area balances with the internal inflation pressure. 3. Reducing and absorbing vibrations and impacts during driving: This prevents early damage to vehicle components caused by severe vibrations. Additionally, tires adapt to high-speed driving conditions, reduce driving noise, and ensure safety, comfort, handling stability, and fuel efficiency.
