This is a pair of Interco® Super Swamper® TSL SX 1.55" Crawler Tires. Under official license from Interco® Tire Corporation, Pro-Line is proud to announce our first ever tire for 1.55" size wheels: the legendary Super Swamper® TSL SX! With "almost scale" not being acceptable and access to Interco's® design data, Pro-Line's engineering staff has reproduced the original Super Swamper® in a scale configuration matched by none. The new 3.85" tall by 1.45" wide Class 0 tire is perfect for those ultra-scale 1.55" wheel rigs begging for matching scale tires combined with unmatched rock crawling performance. The full-size Super Swamper® TSL SX features the ultimate tire tread design by pairing the distinctive chevron tread pattern with the famous, trademarked, and patented Interco® TSL (three-stage lug) tread design. TSL is a lug pattern with short, intermediate, and long lugs that are each uniquely arranged, proportioned and spaced which allow them to bite quickly and self-clean rapidly. Each of these details has been faithfully recreated in Class 0 size to fit your 1.55" wheel. Just like the full-size Interco® Super Swamper® TSL SX tires, Pro-Line tires are proudly Made in the USA!
