GENERAL UPKEEP-Tyres
TYRES
The maintenance of correct tyre pressure is a large factor in tyre life and the
steering and suspension of the
car.
Examine the tyres occasionally for flints or other road matter which may
have become embedded
in
the tread. Clean off any oil which may have got
on the tyres by using fuel sparingly. Driving into or over sharp edged
kerbs is liable to fracture the walls of the tyres and should be avoided where
possible.

or special high

testing where a sustained speed of more than 110 miles
per hour is anticipated, it is desirable that the
Dunlop Rubber Company
should
be consulted as to
the need for tyres of full racing construction.
