Bias Ply Tyre
A bias ply tyre has its internal cords arranged in a criss-cross pattern at angles of 30-40 degrees to the tread centreline. This older construction method produces a stiffer sidewall and is still used for some agricultural, vintage, and specialist applications. Bias ply tyres are generally cheaper to manufacture but offer inferior ride comfort and fuel efficiency compared to radial tyres.
