What is a radial tire?
The radial tire was invented in 1948 by the Michelin Tire Company. This type of tire is often referred to as a “radial” since it resembles the spokes of a wheel. A radial tire features multiple layers of reinforcing cords that run parallel to each other rather than crossing over, like those in traditional pneumatic tires. These cord angles allow the tire to withstand greater forces without breaking down.
In addition to being more robust, the radial tire offers improved handling characteristics compared to bias-ply tires. They’re better able to take lateral force, meaning they won’t roll off the side of the vehicle. Radials also provide superior traction and stability because of their unique design.
About the plies of radial tires: A radial tire is designed so that the plies don’t extend across and down the entire wheel. Instead, its plies comprise individual layers that allow them to flex independently from one another.
What is a bias ply tire?
The earliest automotive tires, pneumatic tires, were all bias-ply tires. They had no internal air chambers. Instead, they relied on the pressure within the rubber itself to keep the tire inflated. You’ll find that the plies are laid out in a layered, angled crisscross pattern. These early pneumatic tires were all bias-ply tires.
About the plies of bias ply tires: In a bias ply tire, you’ll find that the plies are laid out in a layered, 45-degree angle, crisscross pattern. Each ply starts at one side of the tire, heads up the sidewalls, crosses over the crown area, and finishes down the opposite side. This process occurs throughout the tire’s width, resulting in a rigid structure.
Choosing A RADIAL Tire: Advantages and Drawbacks
Radial Tire Advantages
- A significantly increased tread life
- Dissipates heat more efficiently, reducing heat buildup in tires

Radial Tires Excel Over Bias Ply Tires on most of the following aspects
Radial Wins
- Overall Grip and Traction
- Better Handling and Overall Flexibility
- Fuel Economy
- Heat Tolerance: Resistance to Heat Buildup
- Ride Quality: Smooth and Comfortable Ride
- Longer lasting
- Soil Compaction
Bias Ply Wins
- Rougher Surfaces and Low Speeds
- Puncture and Cut Resistance on Sidewalls
- Ease of Repair
- Availability of Much Bigger Tire Sizes
- Price
The radial tires are popular today because they offer superior traction and handling characteristics compared to bias ply tires. Its construction allows for better resistance to heat buildup and cuts. In addition, radials provide exceptional ride quality.
Bias ply tires still have their place in the industry, though – and for specialized applications, they can outperform radial tires, such as in rougher terrains, having more robust sidewalls, repairability, enormous size availability, and in terms of initial price investment (much lower).
So, how do I decide between radial tires and bias ply?
It’s best practice to have a checklist that you can use to help you make that decision. You need to thoroughly understand the tires’ applications, the type of driving, weather conditions, and terrain for your situation. Here’s what you should keep in mind:
- Buy tires based on how much money you want to save over the tire’s lifetime. Remember that the tire life cycle costs include tire replacement, maintenance, and repair costs.
- Don’t just look at the initial cost; consider other factors like tread wear, safety ratings, etc., and always keep your options open.
- Keep track of your tire usage and mileage to see if there are any trends.
- A good rule of thumb is that you spend too much money if you buy a new tire yearly.
In addition, most people only realize how critical load capacity is once they’re faced with a situation where they need to replace a tire: when choosing between two different brands, you want to select the brand with the load capacity that fits your case.
Conclusion
A radial tire offers a much more flexible sidewall structure to reduce rolling resistance than a bias ply tire. With less rolling resistance, the radial tires maintain their ideal shape, which helps minimize tire pressure on the pavement or terrain. This reduces overheating in the tread area to help you save on fuel and enhance the tread lifespan.
However, radial tires have their limitations – when damaged, it is recommended that only the tire’s tread centre be repaired since adding patches on the tire’s sidewalls and shoulder ribs compromises safety and will increase the risk of tire damage. It is best to approach your local tire shop for proper instructions.
Therefore, your choice eventually boils down to what’s suitable for your specific case, the particular application and use of the tires, and your short-term and long-term goals.

FAQs
What are radial and bias ply tires?
Radial tires and bias ply tires are two different types of tire construction. Radial tires are built with layers of cord plies laid at 90-degree angles to the travel direction, making them flexible and providing better traction and fuel efficiency. Bias-ply tires, on the other hand, have cord plies laid at overlapping angles, typically at 30 to 45 degrees. This construction offers sturdiness and is often used for heavy-duty applications.
Which is better, bias ply or radial?
The choice between bias ply and radial tires depends on your specific needs. Radial tires are generally better for most modern vehicles as they offer improved fuel efficiency, handling, and a smoother ride. Bias ply tires are preferred in heavy-duty and off-road situations because of their robustness and load-carrying capacity. So, it’s not about one being better than the other, but rather which is better suited for your vehicle and intended use.
Do radial tires have ply?
The radial tire has a ply, but its layers are constructed differently than bias ply tires. The radial tire has cord plies that run radially across the tire, providing flexibility and stability. This radial construction is why they are called “radial” tires.
What is a radial ply tire?
A radial ply tire has its cord plies laid in a radial or 90-degree pattern from the centre of the tire to the outer edges. This radial construction allows the tire to flex more, resulting in better traction and fuel efficiency. Radial ply tires are commonly used in passenger cars and modern vehicles for their superior performance on the road.
