I was running 17X6.5 OEM hilux steelies steelies without spacers on the PZJ70 but they were just a hair under 4" BS if used a ruler to get rough measurement. I never could get official Toyota specs for that wheel. @Honger is running the exact same wheel currently on his troopy so he could...
3.21” is factory BS for my OEM 15x7” wheels because the offset on those is -20.
3.5” BS has always seemed to be a safe number however.
Is it actually documented anywhere that 3.5” is factory BS for the older 70 series (before coil, 5 lug)?
