HERE'S HOW a tire and "Self Healing" Seal-o -matic Tube would look under General Elec tric X-Ray fluoroscope. No air lost with nails and screws driv en clear in...and pulled out! HEALS EVEN BIG RIPS THAT COULD MEAN "BLOW-OUT"I Actual gash through tire and into Seal-o-matic Tube...the tire still safely holding its air! An S ordinary tubewould almost surely have blown out. But this tube is 60 % stronger... toughened and made extra heat-resistant with Duramin, like Goodrich Silver town Tires... and built round, not packed flat to be blown up and weakened by stretching. SEAL-O-MATIC INNER TUBES really give you 2-Way Safety... as letters from users constantly prove. The man who sent the original of that picture at the left said he "will never drive without Seal-o-matics." Others report not only amazing freedom from trouble, but really big money savings. 100,000 miles without a flat. 11,500 miles without even adding air. Repair expenses (for a whole taxi fleet) reduced from $90 to $9 per month. Tire mileage increased 50%! Names and addresses of these users are available on request. But many thousand more drivers are going to start new records of safety and savings this summer ... with Seal-o-matics. Join them, and enjoy driving with confidence nothing else can give you!
