The Jetko Sting 1/8 Buggy Tires which comes with lightweight grooved cell inserts.
The Sting tire has been designed to fit between block in and Marco
when you have a slightly dusty surface, but you need better wear
characteristics due to an abrasive surface or a surface that is
polished and creates lots of wheel spin.
The pin size and spacing has been adjusted to give more room for
dust to clear the tread pattern yet still have the pin density across the
carcass to give it great wear characteristics
