The Traxxas Weld Gloss Black Rear Wheels & MT Tires (Part #9475) are a ready‑to‑install rear wheel and tire set designed for drag‑oriented RC applications and high‑traction straight‑line performance. This pair comes fully assembled and pre‑glued with licensed Mickey Thompson® ET Drag® slick tires mounted on gloss black Weld Racing® rear wheels. Foam inserts are installed to help maintain tire shape and improve traction and stability during launches — so you can bolt them onto your vehicle and go without messing with tire glue.
