Trucks are q great influence in trade
and as the delivery prob
lem becomes more important In busi-
ness expansion II Is essential from
standpoints of dependableness and
economy that the tire equipment be
adapted to the usage in order to yive
maximum efficiency.
Correct size. style. quality. and gem
eral suitableness OF tire equipment
Is quite AS necessary to low-cost opera
ton as selecting a truck Of special de-
sisn. speed. and carrying capacity. NO
doubt many trucks are being used with
out accurate record Of the operating

can only be determined by close check
on maintenance 1t In turn 10 governed
