Motorcycle tire with tread having main blocks and lower height sub blocks
Abstract:
A motorcycle tire is provided that is capable of remarkably improving a traction characteristic and an anti-sideslip characteristic for cornering without deteriorating the mud expulsion characteristic especially on a dirt road. In embodiments, a motorcycle tire has a plurality of main blocks scattered on a tread. Sub blocks are provided between the main blocks. The sub blocks are made of rubber and have a block height H2 lower than that the height H1 of the main blocks. A part of the rubber constituting a top portion of the sub block is removed to reduce the area of a upper face of the sub block.
