So I recently bought a 2006 te510 and it had on it a monster rear tire called Terraflex 140/80. I noticed that the pIpe in the rear had scuff marks on it, apparently from the tire. So I spaced it out about an inch and a half, and yet it still makes contact slightLy. Then I did some research to find out the stock tire size and to my surprise it calls for a 140/80! I am a bit puzzled by this. Does anyone have an idea what is going on here? I was thinking of buying the Pirelli MT21 140/80 but am I going to have the same problem? I appreciate any help on this.
