In those days a tire and tube cost a r o u n d thirty-five d o l l a r s . , . a n d tire c h a n g i n g was a back-breaking job that called for overalls, h a m m e r and pinch bar, plenty of muscle and a sweet disposition. T i r e m a k i n g has c o m e a l o n g way since those days—thanks to t h e p r o g r e s s of t h e r u b b e r manufacturers and also to the efforts of those industries that supply the c o m p o u n d i n g materials. Outstanding a m o n g these is c a r b o n black. For our m o d e r n rubber tires—both natural a n d synthetic —owe to carbon black a high percentage of their great strength, resilience, flex a n d a b r a s i o n resistance, a n d durability. W i t h o u t it synthetic r u b b e r would be useless for tire production !

Since its start in 1920, W i t c o Chemical has constantly w o r k e d to increase the effectiveness of carbon black t h r o u g h r e s e a r c h . . . and is today o n e of the m o s t progressive producers in the field. A m o n g the recent W i t c o contributions is a special "furnace type" black that is essential in the p i g m e n t a t i o n of heavy-duty military and truck tires. O t h e r ' W i t c o developments are special fillers, a c c e l e r a t o r s , a n t i o x i d a n t s , and similar products that improve the quality of rubber products and help to make less rubber go a longer way. Such progressive spirit is typical of the service in chemicals, oils, pigments and asphalt p r o d u c t s that W i t c o renders to the rubber, paint, p r i n t i n g ink, paper, plastic and other industries.
