B. The positive work done by the rubber belt on the tire and the negative work done by the friction force on the tire are equal to the increase of the kinetic energy of the tire. The positive work done by the rubber band on the tire is greater than the increase of the kinetic energy of the tire, so B is correct;
C, the work done by people on the rubber strip is converted into elastic potential energy of the rubber strip, kinetic energy of the tire and internal energy generated by friction; Therefore, the total work done by people and tires to rubber strip is equal to the increase of rubber strip's elastic potential energy, so C is correct;
D. The work done by people on rubber bands is converted into elastic potential energy of rubber bands, kinetic energy of tires and internal energy generated by friction, that is, the work done by rubber bands to overcome people's tension is equal to elastic potential energy of rubber bands, kinetic energy of tires and internal energy generated by friction. So, d is wrong.
Therefore: BC
