The Pro-Line Front Runner Drag 2.2″ Front Tires are a performance driven tire that will aid acceleration by removing some excess rotational mass. These wheels have been designed to be as narrow and lightweight as possible, all without taking away from the scale appearance. The outer bead is a standard 2.2″, while the inner bead is a 2.7″. When combined with the Front Runner Wheels (PRO280303), expect nothing but performance and great scale looks. NOTE: Requires the use of Front Runner wheels (PRO280303).
