The Pro-Line Positron SC 2.2/3.0" Short Course Truck Tires represent the future of Short Course performance. Boasting a futuristic directional tread design, the Positron offers the increased grip and corner speed needed on indoor clay tracks. Its tread design pays tribute to the Electron and ION tires, featuring two center pins boxed in by connected bars, and angled bars for maximum forward bite and strong corner speed. What's more, this directional tire provides another tuning option for racers, as it performs differently depending on its direction. Plus, it lasts longer than other tires in its class.
