Definitions:

Tire Disposal

The process of properly discarding used or unwanted tires, which involves recycling or repurposing to prevent environmental harm.

Radial Tires

Tires constructed with the cord plies arranged at a 90-degree angle to the direction of travel, providing improved strength, stability, and fuel efficiency.

Bias Ply

Bias Ply refers to a construction method for tires where the fabric plies are arranged at a bias to the tread centerline, offering durability and resistance to sidewall cuts but less traction and heat dispersion than radial tires.

Constantly Changing

Refers to something that is in a continuous state of flux or alteration, often without a predictable pattern.
