Reply to "tallest tires most people run on cmc widebody and whats the effect on rpms ?"

I have run 225/50’s on the rear with 6” and 7” wide, 16” diameter rims.  They are very slightly taller with the 6” rims and begin to rub on the underside of the body on hard cornering IF the body is low enough to the ground.  

You can always adjust the rear torsion bars to lift it up enough to stop rubbing on the underside of the body.

I remember someone at Carlisle had a pair of 245X15’s on the rear but the rims were smaller and he had raked the stance to be higher in the rear.  I think they were 40-series tires, too.
