RADIAL AND BIAS TRACTOR TIRES

Bias (diagonal, cross-ply) tire

A pneumatic tire in which the ply cords extend to the beads and are laid at alternate angles less than 90° to the center line of the tread.

Radial ply tire

A pneumatic tire in which the ply cords extend to the beads and are laid at 90° to the center line of the tread. The inextensible circumferential belt stabilizes the tire's carcass.

USE OF LIQUID BALLAST IN TRACTOR TIRES

The traction capability of a tire is directly related to its weight. The heavier the tire is, the more traction it has.

In order to increase the traction power and to prevent possible wear of slipping, iron cast ballasts must be installed on the front or rear side of the tractor or liquid ballast must be applied. Petlas, together with all vehicle manufacturers recommend using iron cast ballasts. In cases which iron cast ballast application is not possible, tires may be filled with liquid instead.

Liquid ballasting should be done by filling in the tire with a mixture of water and calcium chloride without exceeding 75% of the tire.

Using just water without adding extra materials is only possible when there no probability of freeze. However, using only water decreases the effect of ballasting by up to %20. When antifreeze is needed, water /calcium chloride mixture should be used.

The tire must not be filled with water completely, by any means.

Liquid Filling Process:

-Deflate the tire.
-Rotate the tire in to position the valve at the top.
-Remove the valve core.
-Start filling the water according to the instructions in the manual of the pump.
-During the filling process, remove the pump regularly and let the air get out of the tire.
-Stop the filling process when liquid starts to flow from the valve. Mount the valve core.
-Inflate the tire to its normal pressure.

Important Remark:
In tubeless tires, it is recommended to use an inner tube to prevent rusting of the rim.
