Contact RC Tyres are pleased to announce an new range of 1/12th Circuit tyres known as 'J compound'. Over the last 12 months contact drivers have been testing a lot of different rubber types and we are now happy to provide this ready for sale. The new rubber is especially good on high traction conditions where the track is especially grooved in. The tyre will react with less aggression than our original 1/12th compounds, which are good for lower traction conditions. The new rubber type can be easily identified with the new awesome looking gun metal wheel colour. Supplied in neat boxes with compound type and Contact decal.
