This is a pair of two replacement Traxxas Pre-Mounted BFGoodrich Rally Tires, mounted on Rally 12-Spoke Wheels. These tires are fully assembled, glued, include foam inserts and are ready for installation. 

Officially Licensed BFGoodrich Tires 
Traxxas' attention to detail for Rally includes authentic, fully-licensed tire designs that replicate the actual racing rubber used on dirt or gravel rally circuits. The BFGoodrich Rally Gravel tires offer superior traction on pavement, dirt, gravel, and more. The tire's unique directional tread pattern and sidewall design is captured in high-grip rubber, right down to the raised lettering on the sidewall. Available in standard "hard' and race proven "S1" soft compounds to suit a variety of conditions. Standard compound is a long wearing rubber blend that will stand up to abuse on concrete and pavement, while S1 compound delivers incredible grip.  

Rally 12-Spoke Wheels 
Equal parts style and strength, the rally wheels feature a 12-Spoke Rally Replica design, and a variety of colors that will allow you to find one that looks great with your paint. The color is molded in (not painted) for scratch-proof good looks. Fully compatible with factory Traxxas and aftermarket tires, the wheels also feature 12mm hexes and the same offset as Slash 4X4 wheels.
