I'm about ready to switch tires and go to a 255 or 285 size but I noticed that the Dodge factory step that the dealer installed actually protrudes forward into the front wheelwell some and looks like it reduces available clearance especially with the mudflap against it. I noticed on a friends truck that had a different brand of aftermarket steps and his are further back and don't protrude near as far. Still think I have enough room for the bigger tires but just wondered if anyone else noticed this. The Les Schwab 255's are almost 34 inches in diameter.
