High quality tires, such as what linberl suggested, can offer a smooth ride, low rolling resistance and light weight.
I completely disagree. Small wheel bike frames are inherently stiffer than bigger wheeled bikes ( smaller triangles ) and the wheels are stiffer ( smaller radius ). Therefore small wheel folders need more suspension that a standard bike. I don't think balloon tires are sufficient.
