MILEAGE OF TYRES.

DO TO-DAY’S TYRES GIVE LESS ? “ Balloon tyres do not seem to give as long- mileage as they did when they were first introduced.” This is a remark heard more or less frequently among motorists. Apparently many people think that present-day balloon tyres are not as good as those made two or three years ago (states a tyre expert in the Goodyear News).

And here we strike at the very heart of a condition in dire need of "emedy, a condition based upon public misconception and in direct conflict with the actual facts of the case, for it is the fact that tyre manufac--j turers to-day are making the best j tyres they have ever made, and the j best tyres they know how to make, j Steady improvement has been and is j being made in the art of tyre build--iug, and in their several price classes tyres in general use are of better quality than ever before. U is also true, paradoxical as it may sound, .that even though better balloon tyres are being made to-day I than were made two or three years ago, the tyres of to-day do not ap--1 pear to be giving as much mileage. | When motorists find they are not | getting as much mileage as they had j expected it is perhaps logical that j they first blame the condition on the | tyres. Few, if any, of them stop to ; consider that changing conditions ■ under which the tyres are nln may j he the reasoh for the reduced mileage. Here are the conditions mainly responsible in case.’ where balloon

tyres appear not' be giving as much mileage to-day as did the balloon tyres of yesterday:— 1. Smaller-diameter tyres. 2. Higher motoring- speed. 3. Quicker acceleration of cars. 4. Quicker stopping (four-wheel brakes. 5. Underinflatiosu / 6. Overinflation. ,1
