Experimental tests show this not to be so. The Lancia Lambda car wheels had been balanced by the makers. If the car was run with the wheels a few ounces out of balance, it was far more objectionable than our own cars with similar amount of out of balance. We have also proved that the Hispano Suiza car, if the wheels are out of balance, it will develop high speed wobbles. Hs.{Lord Ernest Hives - Chair} | ||
