Sr. No.
|
Radial ply tyre
|
Cross ply tyre
|
Belted bias Type
|
1 |
Plies are running radially straight from bead to bead
|
Piles are running diagonally opposite from bead to bead.
|
The basic construction is like the bias-ply but for strengthening belt plies are added in the tread area the cord in belt run at an angle of 20o to 35o to the centre line of tire tread
