Any suggestions
2010 Rubi JKU 285x75x17,LOD Stubby, 10K winch, CAI
Since I put the tires on I have been averaging about 16-17 mpg with running 35 psi, went wheeling and droped the tire pressure, done the chalk test and settled on 30 psi. Fuel mileage went to 13.5mpg. Will 5 psi cause that change. For you guys getting 18 - 20 mpg what gives and what is the trick. Let me know.
