Rallye rim tire size

That seems like a lot of tire for a 5.5 rim. BFG puts that tire on a 7-8.5" wide rim. They will most likely wear funny if they fit.

I have the BFG Traction T/A on my rallys, but in 195/60/14. Small by many peoples standards but rim appropriate and rides/handles sweet. I'd go up to a 215 tops on a 5.5, but that's just me.
