radial-ply tire
Noun: A radial-ply tire is a specific type of pneumatic tire (an air-filled tire) characterized by its internal casing structure. In this design, the ply cords (the reinforcing layers of fabric or steel) that make up the tire's body run radially, or perpendicularly, from one bead (the edge that sits on the wheel rim) to the other. This construction is distinct from older bias-ply tires, where the cords crisscross at an angle.
The term radial-ply tire is used to specify this modern tire construction, known for benefits like improved fuel efficiency, better handling, and longer tread life compared to bias-ply tires. - Most modern cars are equipped with radial-ply tires. - When replacing your tires, ensure you get radial-ply tires for optimal performance. - The mechanic explained that the vehicle's original bias-ply tires had been replaced with radial-ply tires.
- The term is often shortened informally to radial tire or simply radial.
- You should get a set of high-quality radials for the winter season.
- Radial (noun, informal): A common shortened form for a radial-ply tire.
- I need to buy two new radials for the front axle.
- Bias-ply tire (noun): The older style of tire construction with crisscrossing ply cords, which a radial-ply tire is contrasted against.
- Pneumatic tire (noun): The general category for air-filled tires, which includes both radial-ply and bias-ply types.
- Radial tire: The most direct and commonly used synonym.
- Steel-belted radial: A specific and very common type of radial-ply tire that uses steel belts under the tread for additional strength and puncture resistance. (Note: Not all radial-ply tires are steel-belted, but the term is often used interchangeably in general conversation.)
- Bias-ply tire: A tire with a different internal cord structure where the plies run diagonally.
- pneumatic tire that has radial-ply casing
