This is a pair of 1.9” Super Swamper XL Tires for Rock Crawling. Under official license from Interco Tire Corporation, Pro-Line is proud to announce the 1.9” TSL SX Super Swamper XL in the legendary G8 compound. With “almost scale” not being acceptable and access to Interco’s design data, Pro-Line’s engineering staff has reproduced the Super Swamper in a scale configuration matched by none. The new 1.9” XL is perfect for scale crawlers that want maximum ground clearance and unmatched rock crawling performance.
