I went to larger E rated tire as I tow a 9,000 lb. boat, the OEM tire was susceptible to vehicle sway due to lighter side walls. I was surprised how well the vehicle handles and rides with the stiffer side walls when not loaded, provided I keep my tp at 38 PSI. The meatier tires has given the truck a more masculine look which can be seen as a bonus. Going with the larger tires, there has been no rubbing in the wheel wells, there has been a 10% drop in mileage, but with the truck being an ecodiesel, the mileage is still awesome! I definitely would buy these tires again!
