I have 305 tires. I just wonder if the MPG thingy in the instruments is right?

If you have different than stock sized tires and it has not been corrected electronically, your odo/speedo and mpg readout will all be inaccurate.I have 305 tires. I just wonder if the MPG thingy in the instruments is right?
How do I fix that?If you have different than stock sized tires and it has not been corrected electronically, your odo/speedo and mpg readout will all be inaccurate.
Either with the AlfaOBD app, you can change the tire size in there. Or you can get the truck tuned by a reputable tuner but that's very expensiveWaiting on wife to get home to see tire size exactly. I they are bigger then stock. How do I reflash the computer?
Most dealers, and many tire shops, have the ability to set your tire sizes so the Speedo etc read correctly.Either with the AlfaOBD app, you can change the tire size in there. Or you can get the truck tuned by a reputable tuner but that's very expensive

Agreed, I'd never want my wife to walk or bike to work, especially if it was a higher-traffic area.Some of us like to not have to sleep with one eye open!
Not really wanting another vehicle. I hate car payments, more insurance cost, property tax cost. I just want the MPG monitor on the instrument panel to read as close to accurate as possible.Agreed, I'd never want my wife to walk or bike to work, especially if it was a higher-traffic area.
That said, it might be a good idea to look into a different vehicle...this is a PRIME example of when an EV would be useful.
As many have pointed out, it probably IS reading relatively accurately for how it's being driven. The 6.4 is not a 2-mile commuter engine. It is a gas workhorse, and you're probably barely getting to speed before you're slowing down again, and it's NEVER getting up to operating temperature. It's definitely not getting hot enough to burn off deposits in the catalytic converter unless you're taking it out on longer drives.Not really wanting another vehicle.
