14 THE COLLIERY GUARDIAN. July 5, 1918. EXTRACTS FROM THE LETTERS OF A SOLID TYRE USER TO HIS SON. “You’re right! I know you’re not one of the too proud to learn sort and you’ll learn some- thing about solid rubber tyres by the time you’ve got that haulage business where you want it. You’re short-handed, of course—who isn’t? And these lorries of yours are kept busy.—You’re overloading them, my boy: you can’t humbug solid tyres—they’ll prove to you pretty soon that it doesn’t pay. You bought Dunlop solid rubber tyres on my recommendation and I don’t budge an inch! They’re like everything else—Dunlop solid rubber tyres, they’ve got their breaking strain. You couldn’t work 20 hours a day indefinitely yourself and not break up. Why not follow the schedule of maximum axle loads the Dunlop Rubber Company have prepared? It’s their job to see that the tyres give you satisfaction. I learnt a long time ago that the camel whose back was broken by the last straw had been overloaded regularly ! ” DUNLOP RUBBER CO., LTD., Founders of the Pneumatic Tyre Industry.
