A Comparative Study of Radial Tyres for Bikes Counter to Bias Ply Tyres

Tyres have been designed to deliver optimum performance and durability for various terrains, weather conditions, and other factors. Two-wheelers typically come in a wide range of styles. Tyres is classified into two types based on their construction and attributes- radial tyre for bike and bias ply or cross-ply tyres.

Radial Tyres

A radial tyre for bike is made up of transverse radial plies that run perpendicular to the direction the tyre rolls or travels. This function aims to decrease heat accumulation and give a comfortable ride. Radial tyres are made so the plies are arranged radially, resulting in a flexible tyre wall.

The Honda VF1000R was the first stock motorbike to use radials. The beast weighed 524 pounds and travelled 150 miles per hour. Unfortunately, biased tyres were unable to cope. Radial tyres were distinguished by their manufacturing method and material. Radial tyres are commonly used as Superior Grip Motorcycle Tyre due to their improved cornering capability and stability at higher speeds.

Thanks to technological advancements, combining multiple compounds on the crown and shoulder of the tread is now possible. As a result, radial tyres can run cooler, faster, and longer. Furthermore, they provide more wet weather grip than was previously considered feasible. The radial structure makes this tyre sturdy for spirit riding while smoothing bumps with a softer sidewall. These characteristics would be impossible to achieve on a bias ply tyre.

Bias Ply Tyres

Bias, cross-ply, and crossbelt are all names for the same thing: they are all made of the same material. Several thin nylon or Kevlar cables are banded around the tyre at an angle of 35-40 degrees. As one strand is placed across the tyre, the next is put oppositely, resulting in a crisscross pattern.

Bias ply tyres are constructed so the plies are laid diagonally, resulting in less flexible walls. A bias tyre comprises numerous rubber plies that overlap one another. The tyre’s centre tread region and sidewalls are interdependent, and the overlapped plies form a thicker and less flexible layer, making the tyres more susceptible to overheating.

To begin with, the tyre’s thickness is uniform around its whole circumference, resulting in a sturdy sidewall. This added strength provides the bias tyre with superior puncture resistance. The biased structure and sturdier carcass can withstand severe loads while providing high mileage before replacement. The tread is designed to wear evenly from centre to shoulder for consistent handling as the miles pile up. The cross-ply or bias tyre, w hich is given as original equipment on Harley-Davidsons, is still one of the most popular replacements for cruiser motorcycles.

Off-road bikers prefer bias ply tyres like the MX33 and MX53 because they are more durable and work well with tubed spoked wheels. Because these are not street legal, Dunlop’s unique innovations improve grip, slide control, bump absorption, and greater resilience for dirt riders. Although bias-ply tyres can occasionally offer superior traction, radial tyres are frequently linked to improved cornering grip and stability at higher speeds, making them the Superior Grip Motorcycle Tyre.

Radial Tyre Advantages

The benefits of radial tyres as compared to bias ply tyres include the following:

  • They offer good steering control because of the flexibility that radial tyres give, which improves vehicle control.
  • Because they have higher grips or traction on the outer portion of the tyre surface, radial tyres provide better sensitivity of contact with the road surface.
  • Because of its flexible sidewalls, which conform to the road’s shape and absorb bumps, they offer superior driving comfort.
  • When travelling at a greater pace on an unproblematic stretch of road or a smooth Highway, radial tyres produce less heat.
  • They provide considerable resistance to harm from the tread and
  • A better graph in terms of the fuel efficiency of the bike.


Most cars and driving situations are better suited for radial tires; however, some applications, such as off-road and older vehicles, might be better fit for bias ply tires. You may contact Metro Tyres, the leading manufacturer of motorbike tyres, when you are confused with the choices.
