| BY6-P15.7.20. contd. - 3 - faulty factor in this combination would be the loose flange, but Mr Hives has tested out the various types and recommended the Goodyear principle, as the design of this type obviates any chance of the rim coming adrift when the tyre is deflated. Our memo EY16-P19520 covers practically the same ground as the above, with the exception of Michelin disc wheels suitable for straight sided tyres. We would like you to refer to this as it was very clear on all the points dealt with in same. BY.{R.W. Bailey - Chief Engineer} | ||
