Effective January 2010 General Technical Information For optimum tire performance, proper inflation pressures for the loads being carried must be maintained. The proper inflation pressure can be found in the load and inflation tables of this book. Air pressure of all tires should be checked and corrected weekly with an accurate inflation pressure �� will increase due to the normal build-up of heat during operation. For this reason, tire pressures should be checked while cold. Do not bleed air from tires while hot. This will result in an under-inflated condition. �� over-deflection and may result in tire deterioration. �� following manner: A) TRUCKS WITH TWO AXLES, FOUR WHEELS: �� B) TRUCKS WITH TWO AXLES, SIX WHEELS: �� with bias ply tires providing tires of the same �� G. Inflation Pressure H. Tire Mixing I. Dual Matching Tires in dual assemblies should be matched with regard to design and dimensional tolerances as noted below. Improperly matched duals may result in irregular wear, rapid wear, vehicle mech anical problems and premature tire failure. Failure to match tires in a dual assembly may result in sudden tire destruction.

Any tire known or suspected to have been run at 80% or less of normal operating inflation pressure and/or overloading could possibly have permanent structural damage (steel cord fatigue).

Rotation patterns, such as those recommended by vehicle manufacturers, may be followed. There are no restrictions on criss-cross rotation. Tires having directional type tread patterns should be mounted in the recommended direction of rotation for optimum performance. 42 J. Tire Rotation K.

Branding For many directional type designs it is permissible to change the direction of rotation after the first �� for pattern-specific recommendation. The casing, after retreading, may be run in either direction, as the casing is not directional. The location for branding must be chosen carefully due to the thin sidewall gauge. Many sidewalls have branding panels, or designated branding areas as noted in sketch at left. Branding in the wrong location may result in eventual tire failure. It is recommended that the brand be located ��
