INDIA TYRES FOR THE BENTLEY. We have received assurance from the India Tyre & Rubber Co, that the maximum amount of out of balance tolerated on the 5.50 x 18" tyre is 48 ins.ozs. We should therefore ensure that if these tyres are eventually ordered for the Bentley, which seems probable, any outside this limit should be rejected.
