Thrust naturally increases as you select smaller wheel sizes, while the torque of the motor is independent of wheel diameter. Thrust is most convenient for estimating the climbing capacity of the vehicle, and it is what most people actually mean when they talk about 'torque'. To a first order approximation, the pounds thrust needed to overcome gravity when climbing a hill is simply weight * %grade
