■fib Are your Tyres UNDER-SIZED, by "Two-passenger-weight.” MEASURE theCross-Section Diameter of your Tyres, when new. If they are millimeter Tyres, and not GOODRICH Millimeter Tyres, you will find they are seriously Under-Sized. That Under-Size interprets into less Air-Space than the millimeter specifications of your Tyre calls for. For instance, —you’ll find the “regular,” so-called, “815 x 105 m/m” Tyre actually measures only 815 x 95 or 97 or 98 or 99 or 101 m/m, (according to make) when you receive delivery of it * » ft A FULL-SIZED “810x100” Tyre (up-to-specification) would, for instance, carry 2900 pounds of Car and Occupants,— • at 70 pounds Air-Pressure,—with a correct flattened-to-the-road-section of Tyre not exceeding 14% of the Tyre Cross-Section Diameter. But, a “regular” (or UNDERSIZED) Tyre of this so-called “810 x 100” size measuring only 810 x 92£ m/m, with same 70 pounds of AirPressure,—and same correct flat-tened-to - the-ground-contact-of-14% would carry only 2523 lbs. of Car and Load. That 377 pounds less carrying capacity is equivalent to the average weight of about two passengers, in Car. m m *» TO compensate for such Un-der-Sizing of “Regular” Tyres you would have to do the following:-* In order to cany the additional “Two-Passenger-Weight” represented by the Tyre-Shortage,— -on the proper 14 % -of-Cross-Section-Diameter - contact - with - ground,— you would have to increase your AirPressure, in the Under-Sized Tyres, by more than 1 7%. Thus, instead of a sufficient 70 lbs. to the Square Inch, you would have to carry 82 pounds pressure. If you failed to do this, with the full load, you would Wear out your Tyres about 25 % faster than they should wear, —through the Result of excessive flattening in contact with the road. This translates into a tangible, countable loss, representing about 25°fi less Mileage from your Tyres, or 25% of what they cost you. « • • AND Lo!—When you do increase that Air-Pressure by 12 pounds (or more than 17%) this happens:— You thereby increase the Vibration to such an extent that you approach the Uncomfortable Action, and Disastrous Result to Car, which would be paralleled by riding on Solid Rubber Tyres at 40 miles per hour, over a rough road. There is a ready remedy at hand for this condition! All millimeter Tyres except GOODRICH are UNDER-SIZED,— as the Calipers or any standard Scale will prove. But Goodrich FULL - SIZED Tyres cost you no more than same quality of other metric Makes, —aU of which are UNDER-SIZED. Now what Remedy does this situation suggest? GOODRICH Fob ,Sized U.Z.
