Show Faltering Tractor Spells Lost Money Improper liquid - weighting of tractor tires can causa mora trouble than if it had not bean dona at all, warn farm service engineers. Tests reveal that to obtain maximum maxi-mum pulling power against minimum mini-mum tire wear, tractor tires should be filled with liquid not more than 75 per cent. The reason for this limit is that an air chamber must remain If the tire Is to retain the basic prin-elples prin-elples of a pneumatlo tire that Is, give cushioning and longer Ufa through flexibility and resistance to bruising. Tractor tires 7 per cent liquid-filled liquid-filled still retain brusie-resisting air chamber that absorbs shock and they retain 95.5 per cent of their wear resistance, 4.5 per cent less than a completely air-filled tire. Proper liquid weighting of tractor trac-tor tires results In: 1. Better traction. I. Less slippage and power losa. j 5. Greater drawbar pull. J 4. Slower tread wear and longei tire life. 6. A money saving because costly cost-ly wheel weights are eliminated. |
