I have not experienced this. I keep mine inflated to 40-42 LBS. I also drive in ECO mode 95% of the time and stay out of the throttle as much as I can. Could be driving style?
I used the GPS Truing box as well. same tires. 295/70/19 Recons. I was 70 on speedo and 74 on GPS. one adjustment and I was dialed in. my values ended up being :
...0Axx
39xx...
SImply on MPG observations, 0.5-1 MPG. But all depends on Driving conditions and habits. eco keeps RPMS and gears much lower than normal mode, especially during acceleration on low throttle input. For me, eco keeps me from accelerating as fast, that's likely where you save the MPGS. Both modes...
Yes , from what I could tell, Speedo, Miles to E, and MPG are all understated with oversized tires until you recalibrate tire size module. I dropped to 16 +/- mpg on 34" tires until I recalibrated with forscan.
I am averaging 17.8-18 mpg on my morning commute currently. 40 min , mix of 35mph-55mph zones. This is after a speedo recalibration with forscan and based on Fords onboard calculations. In stock trim I was averaging 19-19.3 mpg on this same drive. It would be worth a hand calc to validate.
I am surprised by your MPG Loss. I went 1" taller (295/70/18) and heavier (60#+ load E Nitto Recons) on my oversized tire and only lost 1-2MPGs depending on City/Highway. After Forscan re-calibration. Now this is on the 3.5 non PB, so maybe that makes a difference?
I have 1.5" of rake remaining after 2" level. Loaded down in pictures below with my car hauler 6,000-7000 lbs depending on gear. rear measured .75" lower than front. Max tow Pkg with no helper springs/bags or WDH
Great to see another oversized tire on the base 18s. Rare and Love it. I like the 2 tone you chose. I went with 295/70. @Majorplane Did you run a forscan edit for tire circumference to fix Speedo?
I thought it was an easy formula? >40 years of age Chrome , <40 years of age sport color match... I started out really wanting color match and against chrome. You see a lot of sport colored bumpers and 20" sport wheel 14th gens on the road. I talked my self into going against popular choice, you...
Leveled on 34 with Stock 18s. NO rubbing or Trimming.
2" Level but still about 1.5" of rake.
295/70/18 Load E (34.3). Tires alone are 63 LBS ea. Stock Tires were 37 LBS
These are the 18s that come with the non sport base lariat trim.
Larger wheel causes Speedo, Miles to E and MPG to be...
I have downloaded the Forscan application. Loaded my license key. Plugged in my OBD to USB connecter. Powered on the truck. Hit connect to vehicle in forscan and I continue to receive this error message. "No adapter found. Please check connection and try again. Has any one had this issue with an...
