| R.{Sir Henry Royce} 235A (150 H) (W.W. 604. 15-7-14) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 0702. -4- Wor{Arthur Wormald - General Works Manager}/Mcr2/B31714. 4,000 miles on the rear wheels of the Demonstration Car; on the Experimental car 2 steel studded and 2 ribbed Continental over-size tyres have run for 6,000 miles and are still being used on the car. * Mr. Haldenby told me verbally that he preferred them to any other tyres that he has used. We shall be glad if Mr. Royce will give us permission to recommend these tyres to customers when they complain of poor results with standard tyres, and yet we do not think the weight of the body sufficient to warrant us recommending twin wheels, which at present are our only alternative. p.
