WHEEL FITMENT FOR HIACE SC 4x4 KZH106

Hi Guys my name is Brian. Just joined the forums today. Im from Sydney and just Imported a KZH106 SC 4x4 from Japan.

I've had a look on this board and the internet for information on wheel sizes and have only came across tire sizes.

Has anyone fitted aftermarket wheels on their 4x4?

Does anyone know what size wheel will clear the sliding door?

I know the standard wheel is 15x6 +35?

Has anyone tried fitting 15x7 -1? or anything similar?

Also i've seen on some Jap sites they can get sliding door hinge extenders to clear bigger wheels or guard flares. anyone know where i could purchase such an item?

Thanks !
