ive been sizing up tyres and i think the biggest i could squeeze under the rear of my ute (standard width diff and standard wheel tubs, just lipped guards) WITHOUT it rubbing would be 215's if i had the perfect offset

so does anyone know of a wheel that has good offset that sits central in the rear guard?

ive heard 200b steelies are pretty good but im not sure? ive got a bluebird steelie as a spare but that sits very close to the leaf spring even with 165 tyre

what about r31 pintara steelies?
i know a few members have them lying around..

how do they sit?

any other good options?
