I've got an '08 xB lowered on TRD's and i'm about to buy wheels. Unfortunately I have no real experience with fitment or knowledge of what kind of offset the xB can handle with my setup. The wheels are
Riverside Stich Mesh
5x114.3
18x8+28
18x9+27
with 225-40 and 235-40 tires.
I know they are about 7% smaller than my current TRD wheel+tires which will cause my speedo to read slightly wrong but all I care about right now is if they will fit.
Responses appreciated! Thanks!

 

215/40R18 or 205/40R18's all around and you'll be good. 215's you'll probably be fine.

 

215/40 up front, and 225/40 out back should work, but you might need a mild fender roll to keep from rubbing when fully loaded with passengers and/or cargo.
