Load Bearing Index
Rolling Radius/ Tyre Diameter
The table below shows wheel and tyre combinations which are very close to the standard 4th generation Honda Prelude rolling radius. There's an additional page showing rolling radiuses (tyre diameters) which may be helpful when deciding the size of wheel required.
I would choose a tyre with a load bearing index of 'V' (opposed to Honda's H). Also, I would use a wheel offset of +50mm (opposed to Honda's +55mm), although +45mm will be fine, and some people are even happy with +40mm.
