pairs or requirements of parts Will be
allowed except to the ignition system
and its parts, though then driver and
mechanic may make other mechanical
roadside adjus tments Tire repairs and
parts may be furnished by and carried
on tire makers supply cars, and tire
makers helpers may fit tires wholly or
in part, but tire makers cars must be
regularly entered I'm the run in order
to participate, as no cars of any kind
will be permitted to participate unless

Before starting the entrants will be
required to present their cars to the
technical committee for examination. to
determine whether or not the condi-
tions have been complied with. The
cars will be examined again by the
committee at the end of the run. Where
the car is driven with magnetic, for
which an extra charge is made, the
amount will be added to the price of
the car at the time of entry. Any man
ufacturer or agent entering a stock
machine must agree to sell it at the en-
tered price, and imported cars must be
entered at their selling price in this
country.
A liberal time schedule and time limit
will be provided to suit the different
classes and powers, but time lost for
tire repairs will be allowed. Open con-
trolls and checking stations will be
maintained, with motorcycle couriers to
observe and report any infraction of
the rules.

WHY TIRES WEAR OBT
NJ. Michelin of the MicheIin tire company is
authority for the. statement that 1.-THE total
travel of which q tire is capable is inversely
proportional to the cube of the weight which it
carries. For example, IL the load Is doubled
by eight, and increase In weight of per
cent will cause an increase of wear and tear OF
10 per cent" This is food for thought for
the automoblist Some, for supposed economy s
sake, buy the smallest tire to lessen the original
cost. Others will overload car. thinking that
the additional weight be carried easily but
1t can be seen from the statement of such an
eminent authority Michelin that the lighter
the load carried the less the tire expense. If
one uses tires built to carry 1000 pounds on a
car weighing 1000 pounds the life Of the tire
will be twice great that of q 2, 900 pound
Ecarrying capacity tire.
