Bumped up 2 sizes on my 2020 F150 with a small leveling kit (34” tires). I’m off about 2.5mph at typical 60-65mph highway speeds, so I just drive a couple mph slower than before. I generally don’t push it anyway, regarding the thin line of ticket vs no ticket. Have not needed any shift point mods with the 3.5EB and 10spd. Power delivery is not much different, as there’s a good bit of torque down low. Lost about 2mpg from the worn-down 32” SL-rated factory tires when going to the 34” E-rated AT tires (20.5 vs 18.5).
