Radial vs Bias-Ply Tyres: Which Should You Choose?

If you’ve ever seen us refer to PCR tyres, or seen the term somewhere else, then you may already be familiar with the word ‘radial’ in relation to tyre design. What many drivers don’t realise, however, is what a radial tyre is – and what the other option is.

This blog is all about comparing radial tyres with bias-ply tyres – comparing the way they are constructed, their functional practicalities, and which is the best option for different types of driver.

What is a Radial Tyre?

A radial tyre is the most common type of tyre that you will find on the passenger fitment market today. Made up with an internal steel core, onto which of a series of cords are set at 90-degrees from the direction of travel, these tyres are both more stable and more flexible.

The radial tyre is an invention that stems from the history of the premium Michelin brand, introduced by the brand in 1946 and then patented. Radial tyres are the gold standard in everyday and functional tyres, offering benefits that include:

• Even tread wear and a longer tread life
• Reduced rolling resistance which improves the sustainability of tyres
• Smoother and more comfortable driving experience
• Better grip, traction and handling

In short, the majority of tyres that you will come across when seeking a standard and reliable everyday tyre will be of radial design. Among the top radial tyre manufacturing brands, drivers are often drawn to the status of premium brands like Michelin and Bridgestone, or the affordability of mid-range brands like Hankook and Apollo.

What is a Bias-Ply Tyre?

A bias-ply tyre is the kind of tyre that you will find fitted to construction or more industrial vehicles. It is constructed using a series of fabric layers, that are arranged diagonally across the tyre to improve its strength and durability.

The end result is a tyre which is much firmer and stiffer to the touch, distributing weight and tension evenly across the surface of the tyre. As such, these tyres are most often found across off-road vehicles and machinery, which require stability and superior resistance to damage with the benefit of reinforced and incredibly strong sidewalls.

Some of the top tyre brands that manufacture bias-ply tyres include Mitas, Deestone, Petlas, and Alliance.

How Do The Two Compare?

Wondering how best to compare radial and bias-ply tyres, without an engineering or mechanical degree? Don’t worry, we’ve done the hard work for you!

Bias-ply tyres are stronger and firmer, and demonstrate superior load capacity and off-road performance, especially across more challenging terrains. In contrast, radial tyres are more comfortable, are designed and built with fuel efficiency in mind, and boast improved grip and handling for everyday driving needs.

Choosing between the two tends to depend on what you are driving and where, as well as how you prioritise strength as opposed to comfort and durability. Radial and bias-ply tyres are built differently, with each boasting its own ideal application and setting. Keep reading as we dissect exactly which tyres you should choose depending on your driving style and vehicle.

Which Tyres Do I Need?

If you are seeking tyres for a modern, everyday car, then you should stick with radial tyres. These will see you through tens of thousands of miles of driving, will provide optimum comfort and will ensure your vehicle is safe and stable across different terrains.

Bias-ply tyres are for those who are seeking fitments for an industrial vehicle, for a trailer, or for a heavy-duty vehicle that requires additional strength to support a high load capacity. These tyres are tough and built for off-road use, but do not provide the same comfort or fuel efficiency and so do not match the needs of most everyday drivers.
