why no dual compound tires?
 

why are there no tires with duall compounds? a stiffer sidewall and softer tread? i know many have made their own(i.e. rock lizards) but why are no companies making them? or possibly thicker side walls and thinner under the treads

Only a few team drivers have them but the new soon to be released Losi Rock Cutters have a sturdy side wall construction and a soft contact surface. Giving excellent side hill preformance and still pulling hard in forward climbs. So your wish is coming true soon. Dealers here on RCC are taking preorders now.

You mean rock carvers? In the white compound with internal ribbing
