Rear wheel fitment
 

I know the rule of thumb is a 10" max rear wheel. What about a 10.5 et 32 with a 255 tire?

I think they'll fit. I'm running 18x11 et45 with a 13mm spacer so it's effectively et32. I've seen another member running 20x11 et52 with a 7mm spacer for an offset of et45. I think he was able to fit them with a higher offset because from pictures he looked to be running less negative camber than I am. It will be a relatively tight fit with with 10.5 et32 but I think it is very doable.

That's a lot of wheel for that tire. Better fit are 275/35/18 or 285/30/18.
