The way <R08> reads,

ROBOT wheels, tracks, and other parts intended to provide traction on the carpet may be purchased or fabricated (“traction devices” include all parts of the ROBOT that are designed to transmit any propulsive and/or braking forces between the ROBOT and the FIELD). In no case will traction devices that damage the carpet or other playing surfaces be permitted. Traction devices shall not have surface features such as metal, sandpaper, hard plastic studs, cleats, or other attachments. <snip>

I doubt inspectors will allow a chain that contacts the field. Chains close enough to the circumference of the wheel as to contact the field on a bump will provide (however small) propulsive and/or braking forces to the robot. Chains are made of metal, hence they are prohibited as traction devices. I would also worry about lubricant in the chain transferring to the carpet, thus violating <R36>.
