Before Picking Up A Tyre, Know The Difference

Radial vs Bias

Tyre is an essential part of your ride, as it is the only component of your vehicle that has to face every sticks and stones that fall on its way. So, when you are picking up tyres for your ride, tyre construction should be taken as primary count, than just getting the right size and right grooves according to the needs.

Before radial tyres, all motorcycles rims were grabbed by bias tyres, but as racing, cornering and fast rides became more powerful and overheating became more frequent, it became crystal clear that we need better technological tyres. Michelin revolutionized the world of tyres when in 1946 it introduced us with the radial tyres. It put Michelin way ahead of its competitors in the market. Buckle up for some discussion about the difference between the radial and bias tyres.

The main difference between the two tyres is in their belt construction that leads them to deliver different functions and performances.

 Radial Tyres

Bias Tyres

·      In radial tyres the belts that are generally made up of steel are placed at 90 degrees along the tread line, this allows the tread and the sidewall of the tyre to work independently.

·      In bias tyres, the belts which are generally made up of nylon are placed 30 to 40 degrees with each other along the tread line. The multiple lapping in the tyres tends to connect the treads with the sidewalls.

·      As the sidewalls and the treads work independently during the roll, there are lesser chances of sidewall flex and are more contact with the ground.

·      Due to the connection of sidewalls with the treads at the internal construction, the tyre is stiff and causes less contact with the ground and may result in overheating.

·      With radial technology, the tyres have larger tread curves and low sidewalls.

·      Bias tyres has tougher construction than the radials and has higher sidewalls.

Both tyres have their pros and cons:

Radial Tyres Pros

·      Radial tyres provide higher puncture resistance because of its tougher internal construction.

·      Radial tyres are good for high speed motorcycles due to wider treads, the tyre help to remain stable even at high speeds and when hitting sharp corners.

·      If the tyre wears out, it wears out uniformly all the ways round because of its uniform contact with the ground.

·      The tyre can bear high speeds.

Radial Tyre Cons

·      Tyre noise increases because of hard treads.

·      Sidewall is affected by curb impacts.

Bias Tyres Pros

·      Cross internal construction lead to tougher sidewalls of the tyre.

·      Bias tyres are generally less expensive than the radial tyres.

·      Bias tyres are good for smoother rides.

·      Bias tyres are perfect fit for larger heavier and slower motorcycles like cruisers as the tyre has more robust quality and high load capacity.

Bias Tyres Cons

·      The treads of bias tyres wears out at high speeds.

·      Your fuel economy is effected in a way due to high rolling resistance.

All in all, these two families of tyres perform differently and we have to select tyres according to our need and requirements. Radial tyres are the modern advanced sophisticated tyres but still bias tyres are recommended on certain types of motorcycles. It’s not about time, that which tech is old school and which tech has the new hashtag, but it’s more about what type of motorcycle you are using and what type of tyre is put on and how it is riden.
