Show II TRAVEL BRINGS j TIRE HEATING Not Necessary to 'Reduce Air Pressure on Hot Days Say Experts fcBtf The heat that is noticeable in i ijRtJ J tire after it has been run for a tow hours, is generated by the tire Itself, ifftfljl' due to flexing and bending of fabric' ttuSpf unc rubber. The amount of he.it PrTw5 oepends upon the rapidity and extent jjgatl of this action. An overload d or an underlnflated tire heats more rapidly, HWr'; than a properly inflated and properlj KjU j loaded tire. Similarly, an old tire, i nflra due to weakness is more susceptible, Mlir to this heat producing action lhan a now tire. yilFM Tho strength factor built Into the standard pneumatic tires of today is!
