| Y401 To EH. -> Hs.{Lord Ernest Hives - Chair} WP. from BJ. BJ2/H14.11.25. Out-of-truth Tyres. The following is a copy of DA{Bernard Day - Chassis Design}1/H12.11.25, for your information. B.J. COPY OF DA{Bernard Day - Chassis Design}1/H12.11.25. In reply to your E/H/H291025, I have discussed this matter with Mr. Royce. He agrees that it would be undesirable to send further instructions to customers warning them against tyres badly out of truth, in view of the fact that they have the instruction as to the balancing of the wheels contained in the loose sheet attached to your note. It is understood that high pressure tyres, as recommended to be fitted to the front wheels, are very much better in the matter of truth than balloon tyres. (Sgd.)
