Tread on Armadillos
Tread on Armadillos
David Moseley
A In this type of construction, the tread is not glued to the carcass but vulcanised under pressure and heat to make the rubber form a bond with the carcass fabric. It appears that the tread formed only a tenuous bond with what looks like the anti-puncture belt underneath. Synthetic threads such as Nylon may need a special coating to promote bonding. In any case, the tread should not separate from the carcass in such a manner. The tyre has failed prematurely and you should demand a replacement.
