Bailey - Chief Engineer} X3536 Hs{Lord Ernest Hives - Chair}2/LG17.7.28. RAPSON CORD TYRES. X3536 We were recently approached by The North British Rubber Co. to try out a set of the latest Rapson cord tyres which they guaranteed for 15,000 miles. We agreed to test them on condition that if we were not satisfied with them after 100/200 miles, we could return them without any charge. We tested these tyres and condemned them on the question of noise and groans at low speeds. They were much worse than the Dunlop in this respect. Hs.{Lord Ernest Hives - Chair} | ||
