I dont know if this has been discussed in this thread. My fuel milage was going down. Started out over 35mpg, then slowly going down to about 29mpg. The rear scorp was worn out, so replaced with half used dunlap 908. My mpg increased back to over 35mpg. Also, I had been tacking about 5k at 75mph, now with different tire, about 5k at 80mph. The gearing is 16 45. Dont really know why or what this means, its just the results so far.
