We have not yet seen one of these spreaders, they are not fitted to the Firestone inner tubes which we have received from America and we do not feel satisfied that it is a good thing to rely on the valve of the inner tube to form the lock. When the car is in the customers hands one would expect to use any make of tyre on the rim. We should like to hear from Mr. Elley what experience they have had with the Firestone and Goodyear rims. We favour the Goodyear rim. We think that it provides an easy demountable rim with safety. From our point of view, the Goodyear rim is also an advantage rim because the Dunlop people in England have adopted the Goodyear rim and are laying down a plant to make their wheels with these rims over here. It would be an advantage if both the English and the American R-R chassis were fitted with the same demountable rim. If the Dunlop Co. keep their promise we shall have standardised and be fitting Dunlop wheels with Goodyear demountable rims for straight sided tyres, before any of the American R-R cars are completed.
