Radial vs Bias Tyres - What's the Difference

Jul 30, 2019 Car Tyres Tips & Tricks PitStopArabia

What do you see when you look at your car tires? Most people see a round-shaped rubber product that is responsible for rolling the car along the road. Very few people understand that the tire does much more than that, and there is more to the tyre than that meets the eye. However, today, we are not here to discuss the various functions of the tire. But If you want to know more about more read our blog on anatomy of tires

In today's article, PitStopArabia focuses on the construction of the tyre, i.e. what type of material and design is being used in the tyre manufacturing process. Two types of tyres are being used today - radial tyres and bias ply tyres. Radial Tires is much more common these days. However, bias Ply tyres are also being used.

Therefore, in this article, we discuss radial and bias tires. Afterwards, a comparison between the two types is made i.e radial tires vs bias tires. Finally, the article discusses which type is better for drivers today.

Radial Tyres

Radial tyres or radial-ply tyres have belts that are perpendicular to the tire. Instead of overlapping, the belts are crossing each other. They feature another belt that is under the tread. It is usually made of steel. In radial tires, the sidewall flex is not transmitted to the tread, which means that the tire maintains its grip in all types of conditions.

Bias Tyres

Instead of steel belts, a bias or bias-ply tyre uses nylon belts. Moreover, the belts are between 30-45 degree angles of the tread centre line. Also, the belts are overlapping instead of crossing each other. Due to this, the tires are less flexible. Moreover, the tread and the sidewall are interdependent.

Which is Better! RADIAL Tyres OR BIAS Ply TYRES?

Radial tires offer better performance, fuel consumption, and comfort over bias ply tires. Although more expensive, savings on fuel and their durability make them more cost-effective. If you own a non-commercial use vehicle, radial tyres are the best option. Most of the tires, today, have a radial construction.

Tyres in the construction and agricultural machinery still use bias tires most of the time. Even owners of classic cars use bias ply tyres. However, if you neither own a classic car or heavy machinery, radial tires are a perfect choice.

What is the advantage and disadvantage of a radial tire?

Advantage

Disadvantage

Better fuel economy

More expensive

Better handling

Less comfortable ride

Longer life

More difficult to repair

What is the advantage and disadvantage of Bias PLY TIRES?

Advantage

Disadvantage

smoother ride

Morerolling resistance(less fuel -efficient)

Better traction on rough surfaces

Less responsive handling

Longer life

More resistant to cuts and punctures

Shorter lifespan

Less Expensive than Radial tires

How to check if you have Bias Ply or Radial tyres?

  • Look at the sidewall of the tire.
  • If you see an "R" between the aspect ratio and rim diameter numbers, then you have radial tires.
  • If you do not see an "R", then you have bias ply tires.

Here are some additional things to keep in mind:

  • Radial tires are more common than bias ply tires.
  • Radial tires are typically more expensive than bias ply tires.
  • Radial tires offer better fuel efficiency and handling than bias ply tires.
  • Bias ply tires are more resistant to cuts and punctures than radial tires.

Conclusion

So, which tyre do you choose? radial tires are generally recommended as the preferred choice for most vehicles and driving conditions due to their superior fuel efficiency, handling, and ride quality compared to bias ply tires. However, bias ply tires have their own advantages, particularly in terms of being more resistant to cuts and punctures, making them a suitable option for off-road driving. After reading the article and considering the comparison table, you can easily determine which type of tire performs better in specific categories. This information aims to help you make an informed decision when choosing between radial and bias ply tires.Stay updated with Pitstoparabia and never miss a beat.
