The 255/75/17's are less rubber, and are used on the jeep wranglers so they make these in larger quantities. End result is a less expensive tire. They might even be different compounds, but its the bulk manufacturing that saves money.Is there a reason why the 255/75/17's are only $97 (@ tirerack) versus 255/85/16 at $175??
I noticed this huge price difference a few days after picking up the 16" pizza cutters! For that price I couldve picked up a set of steelies and MT's and saved a few bucks!
