Casing consisting of rubberised plies, the casing’s main function is to withstand internal/external stresses. However,

above all it must adapt to the varying ground conditions to give maximum grip in the tread area. In crossply tyres, the plies run in an overlapping criss-cross pattern; on radial tyres they run radially. Sidewall Made entirely from rubber, this area between shoulder and bead, is designed to protect the casing from impact and resulting damage to the textile plies. Bead The bead consists of a metallic ring where the casing plies turn up. This is the critical point of contact with the wheel rim and must provide a positive anchorage between tyre and rim. Belt Located between tread and casing, the belt consists of a multiple layered supple fabric. Its function is to create a solid, stable support for the tread thus producing maximum traction, wear resistance and improved efficiency. Inflation and Pressures Correct inflation is of paramount importance for maximum safety and performance and need checking, when tyres are cold, at least once a fortnight and before any prolonged operation. This is particularly important if water ballast is used.

Under-inflation will cause higher fuel consumption, irregular wear, overheating of the tyre, internal damage and ultimately tyre failure. Over-inflation will cause the tyre to be more susceptible to impact damage, lack of traction, reduced driving comfort and ultimately tyre failure. Tyres fitted to 4 wheel drive tractors should be inflated so that the front wheel lead, usually between 1% and 5%, is not affected. Check with the machine manufacturer for exact limitations Excessive “Toe-out” will have the opposite effect i.e. more rapid wear on the inside tread shoulder and in Britain the off-side tyre will be most affected. Field Work/Low Powered Drive Surface cultivation generally involves lighter loads for which proportionally lower pressures can be used. Inflation pressure directly determines the pressure exerted by the tyre on the ground and the resulting soil compaction. Low loads per tyre(for surface cultivation) require a low inflation pressure exerting a low ground pressure and resulting in minimum soil compaction Use and Maintainance Tyres should be regularly examined paying particular attention to the tread for signs of abnormal damage. Bead/rim area should be checked for chafing, rim damage, cracking and misfitting or movement. As tyres age when not in use, specialist tyres occasionally used should be checked for signs of deterioration before fitting.
