smaller tires?

[civic83]

Does anyone make a smaller tire, say a 1.55' rim (as opposed to tamiyas 1.7) with truck style tires? I need undriven fronts and dual rears. Rc4wd makes some 1.55 rims but all the tires that fit are off road style, plus they are only singles with hexes, no bearinged ones for the fronts.

I want to make some 1:14 delivery trucks but they usually have smaller tires compared to rigs and would like to keep all my vehicles in scale. Any help would be appreciated.
