My wife recently picked something up in the road that caused a slow leak in the shoulder of the front right tire of my v. It only had 4500 miles on it, so pissed. Now when I went to change my tire they ordered a yokohams avid s34b for me, instead of a bluearth s34bz. Will this effect my mpg, it seems they are essentially the same tire besides the orange oil production process...unless I'm wrong??
