the mini pin 2 rear tire this is a tyre for high grip astro and carpet racing. the new tyre has a thinner wall thickness which is aimed at providing more traction and improved bump handling. the pins have been designed to have more of a radius edge as opposed to the square edge on the previous and hugely popular mini pin tyre. this allows the tyre to work perfectly straight from the packet without the need for bedding in. this pre-glued tyre is supplied with our medium foam insert.
