1930 Cadillac Brochure Front Cover - GM Heritage Center

The LaSalle line this year will have two sites of wheels
and tires. The standard wood, with the conventional type
carrier, will be a 19 tt wheel and take a tire of 6.50-19.
All other types of wheel equipment on LaSalle will be 18"
and take tire 7.00-18. As in the past, only United States
tires will be offered on the LaSalle line. As in the Cadillao,
we are prepared to supply demountable wood wheels, with
the spare on the rear as well as fender wells. Wire and diso
will be available with the spare dn the rear or two spares
with fender wells. No provision has been made for the carrying
of two spares on the rear. If we are able to offer a
special adapter at later date on Cadillao, it will also be
available for LaUalle.
The standard gear ratio will be 4.54-1 for all models, with
the exception of the Seven Passenger Sedan and Seven Passenger
Imperial, whioh we would reoo?mend be equipped with 4.91-1.
These axle ratios should apply almost universally with the
exoeption of the few localities where there is considerable
mountain travel, or added power required. For high speed work,
we have released a 4.00-1 to be supplied only on the Roadster,
Phaeton, Two Passenger Coupe and Convertible Coupe.
