What is the difference between radial and bias ply tires, and what are their respective advantages? The main difference between radial and bias ply tires is how they are constructed. According to For Construction Pros, Radial tires are constructed in two parts. The casing has one layer of rubber-coated steel cables that arc from one bead to the other. Then several rubber-coated steel plies make up steel belts that are placed under the tread to stabilize the crown. These belts resist cuts and punctures.
For Construction Pros also details how a bias-ply tire is made of layers of rubber-coated, criss-crossed plies of fabric placed at angles of approximately 30 degrees. Nylon is the commonly used fabric. The tire is constructed to form a single working unit, as opposed to the multiple parts that make up the radial ply tire. Check out the below image to see a detailed visual comparison of the differences in construction between the two different types of plies.
Radial Tire Advantages
- More efficient fuel consumption
- Improved traction and flotation
- Improved cut resistance in the tread area
- Built to run cooler than bias tires
- Longer tread life
Bias Tire Advantages
- Crosshatch construction provides stronger/tougher sidewalls
- Usually much easier to repair when damaged
- Due to the design of the tire’s construction, bias ply want to roll straight as the trailer itself often does
- Generally less expensive
- Potentially smoother ride
The above list of advantages were compiled using information obtained from articles by For Construction Pros, Recstuff.com, and eHow. All three of the linked articles are great resources for finding out more info on both radial and bias ply tires. They are worth a read!
