Pro-Line Prism Carpet SC 2.2/3.0" Front Short Course Truck Tires feature tons of Ultra-Sharp Prism shaped Pins in the middle of the tire combined with Wedge style pins on the outside for incredible steering on small and tight carpet tracks without the edgy feel of full pin tires. The pins on the Prism are slightly smaller than the original Pin Point rear tire but there are many more of them, which results in faster and more consistent lap times. The Prism pins have been positioned with the knife edge pointed front to back and side to side for maximum grip and to stay sharp even as they wear down. The Prism Front tire perfectly pairs with Pro-Line's Prism SC Rear tire for ideal carpet racing performance.
